Make Html Element Empty
Oct 27, 2009I am looking for a method to make a html element empty (no innerHTML). This would be pretty easy if it weren't for IE. IE has the bug that innerHTML is read-only for tables (and some other elements too). So my function
function clearElement(id){
document.getElementById(id).innerHTML = "";
}
doesn't work on tables (and I need it to work on tables). Would there be any other way for me to do this in a way as general as possible. I don't want to bother with 2 different functions for what is essentially the same task and I'm curious how this could be solved in a nice way.

View 1 Replies View RelatedEmpty Array Element Variable Type?
Oct 22, 2009What type of variable is an empty array element? I thought it was undefined, but i noticed that they have different behavior than undefined does:
var r=Array(1);
var s=r.concat([0,"",null,undefined]);
alert (s.toSource()) //==="[, 0, "", null, (void 0)]"
typeof s[0] //==="undefined"
typeof s[4] //==="undefined"
As you can see, 0 and 4 both === undefined. Yet, they don't have the same toSource()...
Is this special type named anything specific? Or more importantly, can it be detected outside of an array as being distinct from undefined? I am thinking this would be the same type as ({}).nonProp ...
I guess the question is actually, "can you tell the difference between uninitialized and undefined"?
Element Offsetwidth Calculation With Empty Space?
Nov 26, 2009I am not able to calculate the offsetwidth of the element which contains extra space in between the characters.for ex. if the element contains "A A" as a innerHTML value - if we calculate offsetwidth as 29 and also if the element contains "A A" value again I am getting the same offsetwidth as 29.While calculating the offsetwidth it is not calculating the empty space.May I know how to calculate the offsetwidth with the empty space because I need to insert the ellipsis (...) if it exceeds original width?
Code snipet
function fitStringToWidth(title,width,className) {
var span = document.createElement("span");
span.className="titleBar-Title-1";

Ensure At Least One Checkbox Or Input Element Is Checked Or Not Empty
Sep 28, 2006I'm currently developing an online work brief, where the user has to
enter details regarding the project into a form. I've come to a section
in the form where the user has the option of selecting between two
checkboxes and an input element. I have to ensure that at least one of
the checkboxes have been checked or that the input element is not
empty. I've come up with this function:
function validateMedia(){
var count = 0;
if(document.workBrief.mediaOnline.checked){
count++;
}
if(document.workBrief.mediaPrint.checked){
count++;
}
if(document.workBrief.mediaOther.value != ""){
count++;
}
if(count 0){
return true;
}else{
alert('Please choose at least one media option');
return false;
}}
I'm sure there is a more effiecient way of writing this.

View 3 Replies View RelatedIE ResponseText Is Empty
Feb 24, 2011I'm trying, to fill a table with data I receive from a Servlet. In Chrome everything works fine. But when I try the app on IE the responseText is allways empty. The following is my JS code (using prototype):
function updateToDeleteTable(){
var url = 'getDefHidConFechaInsercionMayor?plantacion_id='+$('plantacion_id').
options[$('plantacion_id').selectedIndex].value +
"&fechaDesde="+$("dateSelect").options[$("dateSelect").selectedIndex].value;
[Code].....
I know the servlet returns a correct text, because when I enter the request uri in a new IE tab it returns the appropiate html code.
Allso when I check the variable response in the IE JS debugger the resaponse of the servlet is 200 (OK). I realy can't think of anything I'm doing wrong, exept, that maybe there is a size limit for the responseText.

Hiding A Div If A Variable Is Empty ?
Sep 30, 2009I'm using a Javascript gallery (runs on Prototype library) that populates a caption field if the user has entered a caption for an image.
I need a little bit of code to hide the caption's div entirely if the user hasn't entered a caption for a particular image (var 'caption' is empty).
It's the bottom-right white box below the image, you'll have to click over to the second page of the gallery (NEXT) to see an example of an empty one that I want to hide:
[url]
Here's the CSS:
Here's the HTML:
I'm sure this isn't that hard, but I've spent more time trying to get that caption box to hide than setting up the gallery.
