This is a post relate to this post:DOM inside variable with innerHTML?To reduce any ambiguity this new thread deals with the code below.The previous post was more about how DOM can be used in a variable.This one has to do with a similar problem, but more with functions.

How I use $.ajax() for passed argument to php function other file example index.php.
View 1 Replies View RelatedNew to JS. Have ordered some new books, but need to get somethings going in the mean time. What I wanted to do is to link to a new page having a date range input in the form of 6 text boxes, 2 sets of mm-dd-yy, from and to, where the upon loading the page box 1 of the from would auto focus and then auto tab and then post where php could take over on the server side. Setting up the form and the lay out, no problem. Auto focusing went just like expected using the following code, included because on the next step everything fell apart.
Code:
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
So then the wheels came off and in response, began to simplify what was trying to be done to find where the issues were. As far as I can get working is:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html>
<head>
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
<script type="text/javascript" >
function myFunc() {
alert("is this working");
}
</script>
</head>
<body>
<input id="input1" name="input1" type="text" onkeyup="myFunc()" maxlength="2" value="type a No." />
</body>
</html>
First issue with this: When I first get to the page everything is just as ordered. The focus is on the text box and the default value is "type a No." When I press a key onkeyup, I bring up the alert box with "is this working" in it. But when I refresh the page with the refresh button, after clicking the "ok" on the alert box, the character that was typed in is still displayed. If I use the link to the page, or the URL from the address bar, then the page reloads properly with the default value, "type a No".
How do you get the default textbox value using the refresh button as apposed to reloading the page using a link or from the address bar? Using Firefox 8.0 more important at the moment: If I change the script to pass an argument to the function the script crashes. It does not pull up an alert box and freezes. My guess is that I'm doing something wrong on a concept level. Changed the default value of the text box to " ". Looked like to me there was an issue with the size specification and the default string length as you could only enter in a key stroke by highlighting the text and replacing it.
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html>
<head>
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
<script type="text/javascript" >
function myFunc(awe) {
alert(awe);
}
</script>
</head>
<body>
<input id="input1" name="input1" type="text" onkeyup="myFunc("123")" maxlength="2" value="" />
</body>
</html>

How do i use a function to find the average of the values in an array of numbers passed as argument to a function.(using java script) thank you for your help...
View 1 Replies View Relatedhow to you use the result of a function as the argument for another function instead of passing the actual function to it. i.e.
function foo2(){}
function foo(func){}
foo(foo2);
This passes foo2 to foo, can I do foo(foo2()) ? i.e. is the difference between whether a function is passed or evaluated dependent on whether you use "()" after the function name?
I'm using some jQuery to create a playlist for jPlayer. I have all of my songs indexed in a playlist that I have created like this:

I have javascript that sets global variables to true. Here is the code:
<script type="text/javascript">
var count=0;
var castforfood=false;
var sc2mx=false;
var ozrak=false;
var chavodelocho=false;
var jimrising=false;
var day9tv=false;
function justinlive(arg){
if(arg != null){
if(count==2){
ozrak=true;
}
else if(count==5){
day9tv=true;
}}
count++;
}
function livestatus(arg){
if (arg.channel.isLive == true){ .....
The calls to set_status and livestatus work just fine. The problem is calling "justinlive". It only works correctly the first time. The second time, the function does not execute at all. (I tried inserting an "alert ("Hello"); at the beginning of the function, so I know it only gets executed once.)
when my page loads it starts with a confrim box. If "Cancel" is selected then the rest of the page loads fine. If "Ok" is selected nothing after the confirm box loads.Also, it appears that IE and Firefox have trouble with this type of media and Chrome will only play the audio file for about 15 seconds.

I have a parent window where I open a child window.
In that child window I have some js that creates a row in the parent
window, it looks like:
if ( self.opener.document.update )
{
var actTable =
self.opener.document.getElementById("Action_Table");
myTR = self.opener.document.createElement("TR");
myTD = self.opener.document.createElement("TD");myA =
self.opener.document.createElement("A");myA.href =
"javascript:void(null);";myA.onclick = function (evt) {
alert('mike'); }myA.className = "greenlink";
myTEXT =
self.opener.document.createTextNode('click');myA.appendChild(myTEXT);
myTD.appendChild(myA);
myTR.appendChild(myTD);
var lastRow = actTable.rows[actTable.rows.length-1];
lastRow.parentNode.appendChild(myTR);
}
This js creates the row in the parent window ok, but I only get the
alert message when the child window is up. After I close the child
window I get no alert.
I've been asked to pack a very simple javascript function that resides
in the <headsection of a page. I have the function working the way I
want, but when I pack it using this packer:

I am using jquery.ajax() to make a POST call to web server which returns HTTP 201 response for successful creation of object at server. Since 201 is a success I expect the success function specified with jquery.ajax to execute but instead it executes the error function specified with jquery.ajax. Here is how I am using jquery.ajax call.

I have a multistep jquery form that validates user input and then should send me an email. Problem is, right now, I can only get it to validate the first page, then it sends the email before the rest of the pages are viewed. I'm just trying to delay the submission of the form until the "submit_fourth" button is pressed. I've got $25 via paypal for the one who sticks with this one for long enough to come up with a workable solution.
Here is my code I know it's a lot, but I wasn't sure how much would be HTML code is in the second post in this thread (it was just too much to fit in one go).

Does anyone have any coding rules they follow when doing argument checking?
When arguments fail during check, do you return from the call with an ambiguous return value, or do you throw exceptions?
If I try to append a PARAM tag twice I'm having problems:
var.medDiv = document.getElementById("myDiv");
var medObj = document.createElement("object");
var p = document.createElement("param");
p.setAttribute("FileName",this.URL);
medObj.appendChild(p);
p = document.createElement("param");
p.setAttribute("AutoStart","false");
medObj.appendChild(p); // <-- this one
medDiv.appendChild(medObj);
The line with the "this one" comment triggers IE to tell me that it has
an invalid argument. If I change the order of the PARAMs then the new
second PARAM will give me the error. If I move the setAttribute to after
the appendChild I still get the error.
Suppose I have a frame like 123bottom.html and within it, I want to promt
the user for a response (in the <HEAD>) like
var ans = prompt("What is your name?");
and then reload the page (via, say window.location.reload() ?)
using the argument of the value of ans appended onto the url so that, in
effect, say, I am calling the new frame as
123bottom.html?ans=Ike
Can someone show me how I need to call the page again, itself, like this
once I have the value for ans? Thanks, Ike (himself)

Can you pass an array reference to a constructor? I don't know if it's because the syntax is screwy or it's impossible, but the following doesn't work.
// row constructor with array called fields
function RowObject(fields)
{
this.fields=new Array();
this.fields=fields;
}
row=new RowObject(fields);
alert(row.fields[0])
How do you pass an argument to a function.
for example if you have a <span id = "test" onMouseOver ="myfunc(x)>
eg you have lots of differant span id's but you want then all to have a certain background-color with each individual on mouseover event without having to write separate code for each span id
eg <span id=" test2"onmouseover ="this.style.background ='red'>....
Is it true that Javascript has no clone() method, to pass an object by copy of value instead of reference?
If I have an object and want to make an array out of all of its instance variables, I can loop through it and pass its values to a new array, and the class instances will be passed by copy and not by reference?
Example 9.3: References Themselves Are Passed by Value
// This is another version of the add_to_totals() function. It doesn't
// work, through, because instead of changing the array itself, it
tries to
// change the reference to the array.
function add_to_totals2(totals, x)
{
newtotals = new Array(3);
newtotals[0] = totals[0] + x;
newtotals[1] = totals[1] + x;
newtotals[2] = totals[2] + x;
totals = newtotals; // this line has no effect outside of the
function.
}
Note that this rule applies not only to pass-by-reference, but also copy-by-reference. You can modify an object through a copy of a reference, but changing the copied reference itself does not affect the object nor the original reference to the object. This is a more intuitive and less confusing case, so we don't illustrate it with an example.
I had made a form in which dynamic rows are added to a table. Now when i send there values to next page by GETmethod then in between alphabets where space is given + is shown and where new line is there & is shown.

I amreceivingthe following error on IE8:Invalid argument. jquery-1.4.2.js, line 5899 character 5 Now I have used the debugger, and this seems to be the only error it catches. And I realize that I could go through each line of what I wrote and figure out what line triggered this portion of jQuery. However in the interest of making jQuery better, I want to understand this error and fix it in the jQuery file.
