I have built a webshop system in JavaScript(school project)and if I run it , it refuses to work in chrome or internet explorer . In Firefox it works but I get node is null errors on line 343 . But I don't know why
My code:
I'm attempting to run some checks on an input value. Initial HTML:
HTML Code:
<div id="sdvcontainer" class="sdvcontainer hidden inline marginleft20">
<input type="text" id="samedatevalue" value="date of event" name="samedatevalue" class="input jdpicker" onKeyDown="javascript:return dFilter(event.keyCode, this, '##/##/####');" />
</div>
After the page loads a javascript calendar function called JDPicker runs and changes it to:
HTML Code:
<div id="sdvcontainer" class="sdvcontainer hidden inline marginleft20">
<div class="jdpicker_w" onClick="checkDate(this);" onkeyup="checkDate(this);">
<input type="text" id="samedatevalue" value="date of event" name="samedatevalue" class="input jdpicker" onKeyDown="javascript:return dFilter(event.keyCode, this, '##/##/####');" />
</div></div>
My issue only occurs on this HTML that is hard coded into the page. I have several other inputs (same element structure with the divs, etc) added later with javascript using createElement functions and my javascript works fine on those:
HTML Code:
function checkDate(field) {
var divfield = field;
cleanWhitespace(divfield);
var date = divfield.childNodes[0];
var msgcontructor=divfield.parentNode;
msgcontructor = msgcontructor.id;
msgcontructor=msgcontructor+"DMsg";
$(document).ready(function(){ .....
My problem is only in IE (testing with v 8). When I try to get the child elements value it gives me this error: "value null or is not an object". I tried using .nodeValue after that and it worked, but then started giving me errors regarding the .length function "length null or is not an object". There is no nodeLength function that I'm aware of.
im having a little difficulty checking if an XML node has a value, here the code:
var Divs=new Array("artist","bio","img","date","tickets","venue","street","city","country","headliner");
xmlDoc=xmlhttp.responseXML;
for ( nodes in Divs )
[code]....
This always throws up the error: document.getElementById(Divs[nodes]) is null ive tried putting the xmlDoc in a variable then checking if its null but no luck, also tried the same method against "undefined" but no luck either.
I know for a fact that it is an object and I'm pretty sure that it isn't null. I will give you a link to the page that I'm troubleshooting even though it's embarrassingly ugly. Does anyone have
an idea of why it's not seeing the <select name=finish> on Line 183 in <Form Name="myform">?
How can we identify logical errors from other types of errors?

[Code]...
I'm using jsTree-0.9.9a. As a test this is the code i'm using to display the ID
oncreate: function(NODE, REF_NODE, TYPE, TREE_OBJ, RB)
{
if (TYPE === "inside") {
parent_id = $(REF_NODE).attr('id');
alert(parent_id)
}}
This works fine when the parent has no child nodes, however, when a child node exists nothing is returned.
how to read a text file using javascript line by line and separate from special characters in it. for example
Text.txt has
001203=Line one=abc.html
024353=Line two=xyz.html
092434=Line three=hjf.html
i want each column in an array like { 001203,024353,092434 } so total 3 arrays.
getting first line coordinates of multiple line inline element.
Example HTML
aaa bbb ccc ddd <span id="target">eee fff ggg
hhh iii jjj</span>kkk lll mmm nnn ooo ppp qqq
$(document).ready(function() {
[Code]....
Assume that span#target has a line break, when I see a browser. Then I click span#target, above function returns the head of coordinates which second line ("hhh") has. I want to have the coordinates which first line ("eee") has. How can I get that?
reading file in jQuery. Please if anyone knows how to write tome or to the website.
$.get("data/zelis.si.txt",function(data){
$.each(lines, function(n,line){
$.ajax({
[code]....
I did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory. found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so.object.onchange = function() {}i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines

Code:
var parts = rgbString.match(/^rgb((d+),s*(d+),s*(d+))$/); This is the function:
Code:
function rgbToHex(rgbString)

And this is the error:'null' is null or not an object
How do I read a local text file line by line, one line at a time. I got upto opening a file, and can read whole file at a time. But I want to read just one line at a time. May be have a counter of lenght of the file and read only the counter number line at a time.
<SCRIPT language=JavaScript>
var fso = new ActiveXObject( 'Scripting.FileSystemObject' );
f = fso.OpenTextFile( "c:\mytextfile.txt", 1 );

I put a long script but the problem is small.
var book1 = bobj1.value;
var chapter1 = cobj1.value;
var verse1 = vobj1.value;
var book2 = bobj2.value;
var chapter2 = cobj2.value;
var verse2 = vobj2.value;
[Code].....
I don't know if this is written properly: if(bcv[a]!= ""){ The reason this is happening is because the error shows: Error: cobj1 is null Source File: [URL]
I have a user that insists they have web applications that do this, and wants the one I'm building to do it too...
You have a table on an html form. As the user changes one or more fields in a table row and moves to the next line, the changed row should AUTOMATICALLY be sent back to the server and updated in the database.
If the user moves BACK to a line that's already been changed, and changed a field, a popup should display and ask "if the user really wants to change the field". If so, again, it should AUTOMATICALLY be sent to the server and updated in the database...
Ignoring the horridness of making that many round trips to the server and banging the database for every line, is there a way to AUTOMATICALLY do the equivalent of a submit and post the changed table row back to the php script?
My code is in the attachment alex.txt.When i press the button for first time it gives me error: 'null' is null or not an object. But when i press it again or refresh the page and press the button it gives me the result that i expect.When i change the var pdbfile1,2,3 values(for example with 2x4n;3gis;1crn) and press the button again there is the error again and i have to refresh the page again.

I keep getting an error stating "getElementById("ballElement") is null, but I have a div with that exact id. I have looked at the JS script before that line, but found no errors there either. Please take a minute to see if you find something.
[Code]...
is there anything wrong with this script as i keep gettin an error message in IE with menu item 1:
//menu methods
function ehandler(event,theobj){
for (var i=1; i<= theobj.numberofmenuitems; i++){
var shutdiv =eval( "menuitem"+i+".thediv");
shutdiv.style.visibility="hidden";
}
theobj.thediv.style.visibility="visible";
this menu is related to a drop down feature later on!
How do I get to see the details of JS errors in IE? I have some problem in IE that isn't showing up in FF or Opera. Is there an error window in IE that I can open up and look at warnings and errors?
View 4 Replies View RelatedI am in a little over my head here trying to make a template for this PHP script. I am trying to work out all javascript errors.
So far I only have one error on the index page and no other pages. In IE8 at the bottom it shows me the little error icon and when I click it, it shows me:
Line: 2
Char: 18579
Error: Object doesn't support this property or method
Code: 0
URL: http://www.mysocialengine.com/demo/woolton/index.php
I am trying to locate this error in the source code, but cannot figure it out. Can someone maybe take a look at the source and point me in the direction to what IE8 is finding as an error? It's weird that there are javascript errors only on the home page when I use the same header and footer file for the entire web site.
Take a look at my code then I'll tell you what error I get...
The element with that id has been created and I still get this error when I try to style it...
My browser is Google Chrome.
I'm using javascript for my client validation and I would like this to work the way I wanted to. I have three textboxes for last name, middle name and firstname. All the fields are mandatory and if the form is submitted there would be an error to display below the textbox. The problem now is I couldn't show three errors at once. I could only show one error at a time. The error msgs are specific that is "Last name required", "First name requiredHere's my JS structure
function validate()
{
if (textbox1 == empty)
