AND Condition Not Working - Field1 Empty
May 7, 2010
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.

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)

Is it possible to make a file insertion conditional? I now have the code:
'<script type="text/javascript" src="http://www.site.com/showit.js">'
And I wondered if it is possible to make this conditional, something like:
if (mycondition==true) include('http://www.site.com/showit.js');

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.

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 am using jquery.validate.js for validating the forms.
The issue now is I have a dropdown list with values. Say a dropdown has the values 'One', 'two', 'Three', 'Four','Five'.
If the value is 'Three' OR 'Four' . The next 2 input fields are required. Else those are not required. The value will be seperated with optgroups.
I tried with different options but I couldnt find the solution. How to validate this?[code]...

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:

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?

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?
