Why does IE6 ignores JavaScript's return false on a link and how to fix it? Firefox works perfect!
<a href="page1.html" onclick="return test(this)">Test</a>
JS:
function test(obj)
{
if(obj.href=='page1.html'){
doSomething();
return false;
}else{
return true;
}
}
I'm pretty new to js, but i've searched this issue and it seems simple but it's not making sense. I'm trying to make the link dead I have this within a div of my html
<a href="poop.html" id="home"><img src="images/Home_off.gif" width="84" height="40" id="home" alt="home" /></a>
and I have this in my .js file
document.getElementById("home").onclick = changeMov;
function changeMov() {
return false;
}
i tried variations like:
<a href="poop.html" id="home"><img src="images/Home_off.gif" onclick="return false"; width="84" height="40" id="home" alt="home" /></a>
I am currently trying to get an action on the click of a link, and not make it follow the link, just carry everything out in jQuery. Now, if the AJAX request isn't there, it will work as supposed too, but with the AJAX request, it will follow the link, not taking any notice for the return false.

I am wondering about what seems to be a particular quirk in Javascript
that does not allow form event listeners (e.g. "onsubmit=...") to work
properly. In the code below, I would like to set up a function
(doOnSubmit) that is called when the form is submitted.
But there is a "return false;" in the "onclick" of the button. If this
"return false" is removed, the code works as I would hope it would.
With it there, doOnSubmit is never called. Code:
Do you have to use the onClick attrib to have
return false
work?
i.e. is it possible to do
<a href="javascript:somefunct();return false;">
and have the page not reload with 'false' or the browser not complain about
illegal use?
I have a page built with asp.net that includes some "imagebutton"s within a form. These render as input tags with the type set to image. I ahve the onclick attribute set to run a custom javascript function and return false.This has worked fine for the few months the code has been in place and then just recently (within the last few days) it has stopped working for a single network user. They click on the link and instead of the function executing (and the AJAX loading details into the page) the form submits. This makes me think that the "return false" simply isn't executing. The user says that they haven't changed any settings or anything that may cause this issue...
The browser being used throughout the company is IE8 under Windows XP. I have checked the version being used on their comptuer and it is 8.0.6001.18702, which is the same version as the one installed on my local machine which is working fine. Another user has logged into the computer being used by the user with the issues and it works fine for the second user.
i am learning JS at school and it is going pretty well. One concept I seem to be having trouble with is Return False; I understand that it is used when working with boolean types, but I seem to see it in other places as well, apparently to stop a function from doing something. I was wondering if someone had a good reference that explains the difference uses of return false.
View 7 Replies View RelatedI have look through the forum and couldn't find the answer I was looking for, I am working my way through the simply javascript book and wanted to validate a form, if the form doesn't validate then keep the user on the same page and guide it with info, if it is OK then allow it to go onto another page, the javascrpt is on an external page and is called correctly, I have removed all the link info just so that it passes the spam filter. The return false does not seem to work, it will give me the alert box and then still move onto the jowebpage.

The "View All Show Times" href should toggle a show/hide div. All of sudden, it's not working IE 6 (FireFox and IE 7 work fine). This never happened until today. Could an altered browser setting have caused this behavior as I didn't change the code? It looks like return false is not firing.
Links redirect in IE8. I simple want to links to run a function then not go anywhere.
My code
Code:
<a onclick="UpdateTable(9); return false;" href="google.com"> Resources</a>
This will work in Firefox, wont in IE8.Although I cannot reproduct it right now, at some point IE was also working if I had a confirm instead of a false... (weird eh?).
As for my "UpdateTable"
Code:
function UpdateTable(myID)
{
var aa = document.getElementById("displayTable");

If I get rid of all the "innerHTML" it works (so I suppose if I create elements and append them it would work, but im hoping for a solution instead of taking that route).
I would like to code a drop down navigation where the top tier of navigation links is NOT clickable, only the child elements. I am wondering how I would go about coding this using Jquery.

This is my first post here, but reading through the others I'm sure someone will be able to help me.I trying to build a client-side validator before running my validation in php. I have a <form onSubmit="function(login name, login password)"> type deal and in my function, I'm returning false if certain criteria aren't met.
the form's action runs it back to the current URL where I have a php validator activated if the post data is recognized. As of now, both are running, which tells me the form is being submit regardless of that return false.

View 3 Replies View RelatedThis is a simple email form validation, with javascript. I first coded the basic 'have you filled in the field" stuff and that worked great, the error message poped up and the form would not submit until corrected.I then put together a email validation function using reg ex, and things went slightly awry. The reg ex works, so hat is cool, but after catching an invalid email address, it submits the form anyway.Following the logic, you can see that the form gets validate, then the email address is validated, then the form validation function returns true, which is probably why it is submitting with the bad email address.I never seen an example of this, but can you put a called function into an if statement? So it would go: validate the form, then if the email validation function returns true, go ahead and submit.Anyway, here is the code:
JS code:
function validateForm ()

I have a small search appliance on my site that uses the following HTML:
Code:
<form action="/search/search.aspx" method="post" onsubmit="siteSearch(this);">
<input name="q" id="searchbox" type="text" value="Search...">
<input type="hidden" id="search-url" value="/search/search.aspx">
<input type="submit" class="search" name="submit" id="search-submit" value="GO">
</form>
[Code]...
I am attempting to create a stop in the form action if someone leaves the input blank or with the predefined "Search" however, once the alert pops up and a user presses "OK" it still attempt to submit the form.
I am trying to disable the user from being able to go to a new line in my text area. Why doesn't return false work?
View 4 Replies View RelatedI want to implement:
<a href=123 onclick="javascript:return false">123</a>

I have:

function validateForm() {
if (document.forms["form"]["quantity"].value== (+$row['quantity']) {

I am building a registration form and have some javascript that checks the forms user input. This is all activated when the submit button is pressed and the forms onSubmit event is called and runs a function.
I have tested me functions and even when it returns false the form still submits?
Im not sure how i can stop it submiting even if it returns false.
Then onSubmit called this function:
function subForm(theform){
if(checkForm(theform)==false){
alert("it is false");
return false;
}
alert("it is true");
return true;
}
checkForm is working and is throwing alerts when certain criteria is not correct in the form, and then i will get an alert "it is false" so i know that the script is running until then, but the form will still submit?
I'm trying to build my own form validator using jQuery but I'm having an issue. The form throws the alert, but still submits!
