This is my function
function func_name(){
if (field1.value == '' && field2.value == '' && field3.value == '' && field4.value == '') {
alert("All fields are empty.");
} else {
if (field1.value != '') {
if (field2.value != '') {
if (field3.value != '') {
if (field4.value != '') {
alert("All fields are not empty.");
} else {
alert("Field4 empty.");
}
} else {
alert("Field3 empty.");
}} else {
alert("Field2 empty.");
}} else {
alert("Field1 empty.");
}}}
If I set all fields to be empty, the alert display "Field1 empty.".
I have created a registration script in PHP and want a JS feature embedded to tell the user that the 2 passwords they have typed "haven't" matched. If they are identical, then I want the registration to go through as normal, but if there is an incorrect match, then it should stop the script and open up an alert box stating the error. When the user clicks on the "okay" button in the alert box, the script should not try to carry on with the process.
I have seen this feature on a number of registration websites, but I have searched Hot Scripts and some other resources to no avail...
The following method below seems to behave unexpectedly under certain conditions.
$('#myDiv').empty().append(someText); I beleive, (imho), that the empty() function requires some time to execute and interferes with the append() function. I say this because adding a setTimeout() to delay the append() will correct the eratic behaviour.
First post here - I am trying to hide options in a form select field if they are empty. The code below works...but even I know it must be a horrid way of doing it! Anyone care to tidy it up for me? I would learn much from the experience,
I have this web form that I want to validate only four of the fields (these are just input text fields, one of which is for e-mail). The code is supposed to bring up an alert box when a fields is empty and after the user clicks ok puts the focus on the offending input field. For the e-mail box, it is supposed to also check for correct e-mail address form.
While testing the first field, the alert text box appears, I click ok but the page sends the incomplete form to my processing page and causes and error. Firebug says that "field1 is not defined". Honestly it looks like it is defined to me. Can any of you take a look at the code below and see what I am doing wrong? Only my JS code appears below. I've searched online for possible solutions, but the things I've tried produced similar undefined errors. I admit I need more practice in JavaScript (familiar with JS, not proficient)
I want to write an if / then statement and have tried using this:
var MyVarMailto; if (Request.Form("LoanRequest") == "Under $250,000") { if (Request.Form("Organization") == "1") { MyVarMailto = "emailA@address.com"; } } else if (Request.Form("LoanRequest") == "Over $250,000") { if (Request.Form("Organization") == "1") { MyVarMailto = "emailB@address.com"; } } else { MyVarMailto = "emailC@address.com"; }
So basically I have a form that gets filled out and submitted which passes the values to this page. I want to check the values against conditions that you can probably figure out above and then set the variable contigent to those values. I tried using AND after the first condition but that doesn't do anything.
Following have an option in OS: windows/Linux. i only want when user select OS - linux ... then function call otherwise if user select OS - window ... no need to call this function validate() i think it requires if condition in function Validate().... how it is posible to put if condition in function validate()
Currently have a txt input with default value="Your Name". with the on focus event to clear default text.
However if a user doesn't touch the txt box the the script goes on to validate the email box below because we have "Your Name" loaded up. and that passes validation below.
How do I go about adding another condition to look for string "Your Name" to the following if statement.
I tried adding another "||" statement after value.length <2 part and got nowhere.
function checkmailform(){ if ( (document.forms.newsletterform.Name.value == null) || (document.forms.newsletterform.Name.value.length < 2) ) {alert("Input First NewsName"); document.forms.newsletterform.Name.focus(); return false; }else{...
Is there a way in javascript to use multiple if conditions? For example I need something like this: Code:
if( email=="" ) { do something } elseif( !issemail(email) ) { do something else }
I know it would be possible to use else and then another if but since this javascript code is PHP-generated and I'd have about 5 conditions, I can't really do this easily.
I came across something I'm unfamiliar with -- there's an added check for window.location.href.indexOf("http")==-1 to see if the XMLHttpRequest send() completed, i.e.,
if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
Does anyone know why this is done or which browser this (kludge?) is meant for?
I created two forms. In the first frame i had Items with checkbox like names of students etc. When ever i checked on any name It's display on the other frame. Up to know it's fine. But when i deselcted any check box it again display same name.
My requirement is when i deselected the checkbox that particular student name is deleted from the list .

i am trying to have text-decoration applied on some text depending on the value of certain variable. If the value of myvar=0 text-deco =none and if it's 1 then text deco= line-trough...
Kind of the same thing that emails web apps like yahoo or gmail do with mails read or unread if it's unread then email title/subject is bold/strong but if it's read then email title is in normal font-weight...
here is some piece of code i have written to do that
the text on which i want to apply the conditionnal decoration is a table cell (cell2DisplayCell1), the text itself is inserted by the innerHTML instruction!
I tried to introduce the conditional statement with a function displaylinksLineThrough() which is defined in the second block code... Code:
Is there a way to combine selectors with && condition. eg: $('.classname div[att=value]') Requirement is to select all div elements with class 'classname' and (&&)an attribute 'att' whose value is 'value'
How could I add a class to a div that contains a div that contains a link that contains specific text, and name that class based on that link but with hyphens in place of spaces and all lower case? Here's specifically what I'm looking for:
<div class="my-div-one"> h2>Title of this section</h2> <div class="my-div-something-else"><a href="url">My Special Link</a></div> </div>
In the above example, I want to add the class my-special-link to my-div-one. Is that possible? How could I do that?
In the attached code the outcome always defaults to the first test, even if the condition is false. How would I alter the syntax so that both condtions are evalauted?
I have 3 sum fields which I want to change to a red colour if the value is > or < 100. Apparently this is a DAP, but I am using javascript to tweek some of the settings in DAP.

I'm building an application that lets a user enter a text string in a text input box, then I display the text string in a separate division using dynamic html techniques. I use innerHTML to rewrite a div, specifiying the style elements inside the <div> tag, and placing the text string between the <div> and </div> tags. I use the overflow:hidden attribute to keep the text from visibly overflowing.
However I'd like to be able to actually detect that an overflow has occured, so that I can truncate the text string (change the form input element value) so that it contains only the characters that 'fit' without overflowing the div element.
Is there a way to capture the event of a specific DIV element overflowing?
