Just trying to display a javascript alert and for some reason the browser is just displaying the code
I have put the following into a file called test.js but it is just displaying all thie code in the browser - see [url]
I am sure this is something really basic. I have tried this in Firefox and IE
Code:
I hope this is relatively simple. I've looked around for the answer, but I thin think the search terms (update onchange event) are a bit too common...
document.getElementById("tester").innerHTML= "hello";
document.getElementById("tester").onmouseover = "alert('hello')";
You see I'm trying to change an event like I'd change a property. The first will change the text to hello. I'd like the second to change the onmouseover event to display a hello world alert... but it doesn't seem to do anything.
I have a bit of coding that is keeping me up at nights because of it's damn stubborness. All I want to do is pop-up an Alert that says Hello World.
I'm new to coding period so I'm writing verbatim dummies javascript book examples.
Here is the code for the script:
Okay I've done this code , and variations and only have ended up with the same message in firefox "syntax error""quirks mode".In IE 8 I get messages to cryptic to understand.
So what gives? Where is my error in syntax?The code makes sense to me, and I'm following XHTML conventions.:
Most of these characters are not on the standard keyboard.
Here's a successful contrivance, with comments & cautions,
a little page that works in IE6.
<HTML><HEAD><SCRIPT TYPE="text/javascript">
function alt() {
document.all.s1.innerHTML="Current Temp: 68°F";
var txt=document.all.s1.innerText;
alert(txt);
}
</SCRIPT></HEAD>
<BODY>
<INPUT TYPE="button" VALUE="Temperature" onClick="alt()">
<P ID="s1" STYLE="visibility:hidden"> </P>
</BODY></HTML>
comments: The innerHTML property is needed to produce the
character glyph from the entity code. If the entity string
were passed to innerText(in 1st statement) then the code
would remain literal.
This work-around depends on s1 being rendered before alt()
is called. It will not work as immediately executed code,
because element s1 would not exist yet.
cautions: Trying to style alert's display will produce error
msgs. Do not use <B>, <U>, or <I> tags in the argument
string. No Heading tags either.
Strange enough, an inline STYLE, setting font values, say,
does not give error msg, but will not execute either.
Alert ignores it.
You can use <BR> tags in the argument, which give the same
result as
in a direct arg to alert().
In sum, you can tell alert what characters to display,
in what order, and on what line, but you cannot tell
alert HOW to display them.
In this program my basic intention is that as soon as the page loads, an alertbox will be called displaying the ALT value of image.
<!DOCTYPE html PUBLIC
This is my test page.
It doesn't work. When i used plain javascript alert function in body tag with onload event, it worked well.
This (code) implementation just shows the text in strong tag and the image. There is no messagebox displaying the alt message. Please tell me where I'm wrong. I've already downloaded the jQuery library and it lies in the same folder as this code.
I need to display alert when I close the browser window. Now I am using the following code to display the alert. But the alert is getting displayed even I click on any links. But the alert should not displayed when i click the link.

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">[code]....
when the user clicks on the link it shouldn't take them to [url]....instead it should display an alert box. but it takes me to[url]...every time.
I am in the process of learning javascript and I've been looking at this code for the longest time ever. So far I got most of it done. For example I leave all the required fields empty, it gives me the alert message of the first field and not the alert messages of all the others. What I want to know is how can you go through and check the whole form first before submitting and then when there is any error on any field, shows just one alert message containing all the error messages.
Code for the form
<form action="mailto:hummdedum@felloff.com" method="post" name="form" onSubmit="return isFormValid();">
* First Name: <input type="text" name="FName" id="FName" onblur="checkFName();"/><label id="labelFName"></label><br />
* Last Name: <input type="text" name="LName" id="LName"onblur="checkLName();"/><label id="labelLName"></label><br />
* Password: <input type="password" id="pw" name="Password" onblur="checkpw();" id="pw"/><label id="labelpw"></label><br />
*Re-type Password: <input type="password" name="2Password" id="pw2" onblur="checkpw2();" /><label id="labelpw2"></label><br />
I am a: <br />
<input type="radio" name="status" value="fresh" /> Freshman<br />
<input type="radio" name="status" value="soph" /> Sophomore<br />
<input type="radio" name="status" value="jr" /> Junior<br />
<input type="radio" name="status" value="sr" /> Senior<br />
I am taking classes in the: <br />
<input type="checkbox" name="semester" value="fall" /> fall time<br />

My favorite element is:
<select name="element" id="element">
<option value="">select one</option>
<option value="fire">Fire</option>
<option value="earth">Earth</option>
<option value="water">Water</option>
<option value="air">Air</option>
</select><br />
*Birthday: <input type="text" id="BDay" name="Birthday" onblur="checkBDay();"/><label id="labelBDay"></label><br />
*E-Mail: <input type="text" id="email" name="Email" onblur="checkEmail();"/><label id="labelEmail"></label><br />
<input type="submit" value="Submit" />
<input type="reset" value="Clear" />
I want to also validate birthday.. and I tried using regular expression with leap years but the expression is too hard for me to think of. So I am gonna try using split() but I don't know and for the clear button. Since I blur functions, how would I just clear all the blur statements = like a restart of the form and then when the user enters the field the blur function still works?
I am a novice, almost to an intermediate-level JavaScript guy, so much of this is new to me. I appreciate your patience reading this.
I have a routine that creates some HTML on the fly (updateFilters() function) and after the HTML is created, I attempt to access some fields (elements) on the form itself.
I works fine if I place an alert() statement after the HTML is created, but when I remove, the code errors out.
I have tried the setTimeout() statement, but I cannot grab the element --- undefined or null is returned. It seems that the form is the only element I can get a handle on --- everything else is undefined or null...
Here is the code:
function editQuery() {
var f;
var x;
var myForm = document.forms[0];
// Get the row filters that were used in the last query..
for (f = 1; f < 16; f++) {
var filter = eval("myForm.FilterList_" + f);
if (filter.selectedIndex > 0) {
var methodElement = element("FilterMethod_" + f);
var methodIndex = methodElement.selectedIndex;
var savedFilterMethodValue = methodElement.options[methodIndex].text;
var choicesElement = element("FilterChoices_" + f);
var choicesIndex = choicesElement.selectedIndex;
if (isNaN(choicesIndex)) {
var savedFitlerValues = choicesElement.value;
}
else {
var savedFitlerValues = choicesElement.options[choicesIndex].text;
}
updateFilters(filter); // update the filters
// take the saved methods and values and then update the selections
// Alert here makes the code work..
// alert("Try this");
// Wait for HTML..
setTimeout("completeEdit()", 1000);
function completeEdit() {
// Since the object was updated, get the object again..
var methodElement = element("FilterMethod_" + f);
for (x = 0; x < methodElement.options.length; x++) {
if (methodElement.options[x].text == savedFilterMethodValue) {
methodElement.options[x].selected = true;
break;
}
else {
methodElement.options[x].selected = false;
}
}
// Since the object was updated, get the object again..
var choicesElement = element("FilterChoices_" + f);
for (x = 0; x < choicesElement.options.length; x++) {
if (choicesElement.options[x].text == savedFitlerValues) {
choicesElement.options[x].selected = true;
break;
}
else {
choicesElement.options[x].selected = false;
}
}
// Only display next row if f = 2..
// If only one row was used, no reason display the next row..
if (f == 2) {
displayNextFilter(f - 1); // display it
}
}
clearTimeout(timeOut);
}
}
}
Do I have to pass the object (the form, the elements) to the completeEdit() function in the setTimeout() statement?
I'm new here and I have tried to search the forum, but there was nothing fitting to my problem.
I would like to display content in an alert box. Sounds simple, but the content is fetched immediately, so I have no influence on that[code]...
This responseText is quite long and I need to display it in more than 2 lines.
Im doing some security research for my master thesis and am a JacaScript newbie
My group is working on a basic document management system that includes four users. staff member, department director, division chief and clerk. The programming language that we used is PHP.when staff member logs-in on his homepage and uploads a file he must choose reviewer from a dropdown menu that consists of dep. director and div. chief.When he clicks the upload button the homepage of who he chose as reviewer should receive a prompt/alert box upon log-in saying "you have a document to review".For example:if he chose division chief as the reviewer when the person logs-in on his homepage a prompt/alert should display that he has something to review.The code for uploading file is already up and working.

View 5 Replies View RelatedI'm building an online auction system. Each participant will be allowed to post one bid per minute for about 3 hours. Each person's "bid history" must remain visible to him during the entire auction in a scrollable list, and this list must be sorted from high to low bid. These auctions will have upwards of 10,000 bidders and the server will be seriously stressed in dealing with so many bidders posting another new bid every minute. Therefore I want to alleviate any additional stress on the server by storing and sorting each bidder's "bid history" in his own browser -- perhaps in a cookie or maybe there is a better javascript-based data storage container available for this purpose ... ?
This seems like a natural application for javascript because of the fact that only the individual bidder needs to see his own list of submitted bids -- sorted from high to low -- and I'm hoping that javascript can be employed to do this.
1- A bidder enters his bid into a form (example 12345.67) and posts the form to the server;
2- Javascript grabs the posted value and appends it to the cookie or whatever container is storing the bids in the browser;
3- Javascript re-sorts the values and displays them again, perhaps in an iFrame or maybe in another kind of scrolling list on the main page.
Note that these bids will NOT be placed in ascending or descending order (this auction is different from most) and this means the values must be re-sorted each time a new value is posted -- so they always appear sorted from high to low in the list.
I have a series of links in my page, all with its title atribute filled. The thing is that I don't want the browser to show this title whenever i hover those links, but still want to have mi titles in the markup Is there any way to do it?
View 1 Replies View RelatedBasically what I need to do is cause a bit of HTML to only display on a specific page. I have figured out how to do most of the work i.e. figuring out what page that the code is being displayed on, etc. However, for some reason the DOM element that I am using will not update based on the Javascript.
Here is the version of the code that I am currently working on:
<html>
<head>
<script type="text/javascript">
window.onload = function DisplayButton() {
var DesiredPage = 'Page to Display';
//Page that I want the code to display on
var sPath = window.location.pathname;
var sPage = sPath.substring(sPath.lastIndexOf('/') + 1);
//This determines and places in a variable what page that the code will be on
if (sPage == DesiredPage) {
document.getElementById('HiddenCode').style.display = "block";
}}
</script>
<p Id="HiddenCode" style="display:none">Code only to be displayed on indicated page</p>
</head>
</html>
How to display an alert message with a scroll bar attached?
If this is not applicable, then how to display a popup message with a scroll bar, which acts completely as an alert message in its behaviour, meaning that the user can not act on the page except when he confirms the alert?
how to get the alert box to display in text instead. So when the user clicks on the submit button instead of an alert box, the result would display below the button in text instead of an alert?
<script type = "text/javascript">
function validate (form){
var hrs=(form.hrs[0].checked)? form.hrs[0].value : form.hrs[1].value;[code].....
I have been being banging my head against this for hours. I have an iframe that contains XML. All I want to do is display the XML content in a JavaScript alert. Here is what I have figured out.
This code retrieves the XML document object from the IFrame.
So I tried a simple alert on this and I receive the message:
So I think at this time, I have an XML Object.
So I tried this code:
Code:
Running this code, all I get back is an empty alert message which has me confused.
Is there a way i can return an error through my JS which is then displayed in an alert box ?
I currently have this:
Code:
Now in pck.php if i had Echo 'Test';
I want my JS to check something was echo'd and if so - display it in an alert box to the user.... any idea if thats possible ?
function Search( name, category )
{
var sresults = [];
var sri = 0;
if( category != "Any" )

This is probably the weirdest thing I've ever seen. I know the code works since Firefox will output things, but it ONLY outputs when I throw in an alert statement somewhere in the function that gets called. It doesn't matter if it's at the beginning and just says Hi, but then it will run correctly. Without it, Firefox won't go through the function apparently and won't write out the results. I don't understand why this isn't working or why firefox is doing this.
How I would output the day as well in this

View 24 Replies View RelatedI have a classified listing application (php) that shows an alert message on the main page to let the user know if there was an error, if the listing was entered, if a required field was left blank, etc.
the simple jquery code is:
$('#alert').fadeIn("slow");
setTimeout(function() {
$("#alert").fadeOut(3000);
}, 4000);
the alert msg. displays whenever the page is loaded. However, if someone navigates with the forward or back buttons in the browser, or reloads the page, the alert message displays again.
I am pulling my hair out for a solution that shows the alert only once and then does not show an alert again until a new message is generated.
I want to display instruction in an alert box.
I query database to get this instruction. I have an instruction which has semicolons in it.
Ex: NO STATUS ON DEED; OLD NUMBER 805;
How do I display the above sentence in alert box? code...
I tried to display an alert window (avoid pop up since some users blocks it and hence not displayed on onload event in body) But it is not displayed properly like popup window.
