Function Id Is Not Defined, But Correct Input Shows In Testing Alert?
Dec 1, 2010
I have the below function and I keep getting the error Lid is not defined.
<script type="text/javascript">
function loadTips(file,ID,File,id){
alert(file);
alert(ID);
[Code]....
So my alert Lid comes up with txtHintLees, so it is working up until the alert. Which leads me to believe that maybe it doesn't like being wrapped in "", without "" though firebug halts the process. I tried wrapping it in {} e.g. {loadXMLDocRefresh(File,id)} but that wasn't liked either. I'll stop my list of things I tried that don't work now.

looking for some help regarding responseText, so please have a look :) im so mad right now because i have been struggeling for hours :(XMLHttpRequestObject.responseText returns correct value when i do alert(XMLHttpRequestObject.responseText); see linevar fnWhenDone = function (XMLHttpRequestObject) { alert(XMLHttpRequestObject.responseText); };But problem is that i want to save down the response to a variable... so i try to change it into var fnWhenDone = function (XMLHttpRequestObject) { varTest = XMLHttpRequestObject.responseText; };When i try to alert varTest later i get "Undifined"... im pretty new to javascript and have been stuck for hours ...See full code below
var myConn = new XHConn();
if (!myConn) { alert("XMLHTTP not available. Try a newer/better browser."); }
var fnWhenDone = function (XMLHttpRequestObject) { alert(XMLHttpRequestObject.responseText); };

I had a rethink about my problem discussed in this [URL] thread, where the function won't run properly a second time if the page hasn't been reloaded. That one appears not to have a solution, and I was thinking that a reasonable plan B is the following:
a) test if the function has already been run since the page was loaded
b) if not, run the function
c) if it has, reload the page with the onClick, then run the function automatically on reloading.
the problem I envisage is will the page "remember" to run the function once it has been reloaded?Of course, it would be simpler to do it running the function automatically once the page loads, then just reloading if the test comes back that the function has been run already, but that wouldn't work for the first time you visit the page - it would start running straight away, whereas I want it to wait for that first click. Here's the page [URL] I'm working on, if you want to have a look.

I'm trying to learn JavaScript. so what I want to do is have a question at the top of the page asking about a picture. Then the user must type the answer in. So I want to set up the script to recognize whether or not the input is correct and go to a different page accordingly.

I know it's something stupid I'm doing but I can't figure it out. Essentially I'm trying to load two objects with URLs with two websites that can be loaded(displayed) and unloaded(hidden) at the click of a button.
I've spent an hour trying to debug this and I'm at my whits end! I'm doing this with changing the width and height of the divs that contain the objects that will load the websites. But, in Firefox I get an error in the error console saying : loadUnload is not defined. why? code...

I have a selection list that users can choose one value from about 300 different values. I wish to add some cross value vaidations to ensure some extra data gets entered should the user choose one of 50 of these values. Now I know I can write a JS validation individully fo each of the 50 as follows:
if theForm.field1.value=="25" && theorm.field2.value =="" {
alert("Enter field2 value");
}
Then repeat this alidation 50 times.
My question - is there a way to shorten the code to someting like this:
var fieldx = "1, 2, 3, 4, 5"; etc with all 50 values defined here, then something like:
if theForm.field1.value==fieldx && theForm.field2.value =="" {
alert("Enter field2 value");
}

So I have a function, and in that function there are two paramaters: index and newLocation. Each of these parameters can initially either be an integer or a string: The string can only be the values of "first" or "last". I can do a long set of code for both parameters, but I was wondering if there was a way to iterate through the parameters to make the code more compact and reusable.
if(parseInt(index, 10) == "NaN")
{
if(index == "first")
{
//The first index of the array
index = 0;

I'd like to create a quick and dirty validation method for a form. It's not meant to be very secure.
The way I picture it working is this - there is an input field that asks for a password. If the user types in the password correctly, the "submit" div tag will change from "none" to "block". , which will display the submit button. I just am not familiar with JS enough to know if that's possible.
Here's what I'm starting with:

The simplified code below works, and should give you an idea of what Im trying to achieve. The final version will have dozens of input fields so you can see why the below method stinks :D
<html><head><title>Values</title>
<script type="text/javascript">
<!--
function getid() {
[Code].....
Each text input will have A or B written in by the user, which should automatically place that letters associated ID in its partner field. If any other letter is entered the ID will automatically be left blank.
With the above code I'd need to repeat it over and over for each of the dozens of input fields. The final version wont be using simply A/B either but around 50 possible inputs each with their own ID which would make around 1000 possible variations.

I'm making some changes to a google chrome extension I made and am having some trouble. Heres my code on a content script page (removeAttr.js) :
chrome.extension.sendRequest({greeting: "whitelist"}, function(response) {
var whitelist = response.whitelist;
console.log(response.whitelist);//working
});
alert(whitelist);//alerts "undefined"
How do I acess the whitelist variable from outside the sendrequest() function?
Iv tried saving it to a window.var variable with no luck. Iv tried creating a div and assigning it's innerHTML as the whitelist variable and getting it later with no luck. The fact that it's a chrome extension complicates things because i dont actually know if i can create elements from where the script is located.

This is an admittedly convoluted script, so I'm not surprised it's a bit buggy.Basically, I'm arranging several hundred small divs on a page. This code writes each of them onload, and checks urlArray to see if the specific div being written has a function attached to it, then enables onmouseover/onmouseout hand pointer/default pointers to it, and, of course, runs the function onclick.
var urlArray = ["main", "none", "none", "none", ... (snip) ]
var i = 0;
function writeDivs(){[code]....
The script as it appears here runs great in chrome, but Firefox tells me that "main" is undefined whenever I click or roll over the div, and IE says "object expected" when I click."main" is the name of a function defined in an external js file (though pasting the function into the main document doesn't do anything).In fact, the whole of the above script may not even be relevant, since the following doesn't work either:
document.write("<div class='posDiv' id='div"+i+"' onclick='javascript:main()' >"+textArray[i]+"</div>");

What is a cross-browser way to check if a function has been defined?
It seems that this code
if (myFn) {
myFn();
}
executes whether myFn is defined or not. When it is not, a JS error
results.

I have found a useful script at [URL] which shows the date a page was last modified. I have put it at [URL] where it works perfectly. But the same script with a PHP file extension as here [URL] only shows the current time. There is no PHP in the page, but somehow the PHP processor seems to be upsetting it.

when you click the link from the iframe it doesn't work at all in firefox...says the function is not defined.This is working like a charm in Safari ---I have tried defining the function in a dozen different places -- INCLUDING the index.php header and the content item there on the page.Also in the google.blogger header --- NONE work in safari as consistently as what I have got here.I basically hacked a google.blogger widget and wanted to use a submit-form instead of the get-url variables to load the page of the website wth the blogger iframed into the site.
