toggleDisplay(document.getElementById('table2'))
In a table, and I have this javascript function
var rowVisible = true;
function toggleDisplay(tbl) {
var tblRows = tbl.rows;

document.write(tbl);
for (j=1;j<=100;j++){
if(tbl==table+j)document.write(table+j);
} for (j = 0; j < tblRows.length; j++) {
if (tblRows[j].className != "headerRow") {
tblRows[j].style.display = (rowVisible) ? "none" : "";
}}

Executing A Function From String Text
Jul 23, 2005I have an application that navigates through the links in a document,
most of which are "javascript:doThisFunction(args)" type of links.
Using DOM navigation I can find the reference to the javascript
function and store it as a String variable, but is there a way to
execute the function? Currently the only way I know how to do it is
in a series of if/else statements as in:
if (link=="doThisFunction(args)")
doThisFunction(args);
else if (link=="doThatFunction(moreArgs)")
doThatFunction(moreArgs);
... etc.
is there a more elegant way to do this?
Passing The String-name Of The Function To AddEvent
Dec 14, 2006I would like to separate my javascript completely from my xhtml. in the
end there should be only
<script type="text/javascript" src="javalib.js"></script>
in the head-tag to my javascript.
Because I want to use some ajax-requests and other javascript-functions
on my xhtml, I need to dynamically add event handlers to any possible
dom-elements. All solutions I found so fare are for specific, pre-known
dom-elements: like 'all <imgof a certain <span>-class get an
onmouseover event handler'. But I need a function, which runs onload of
the window and dynamically determines, which dom-elments need an event
handler and which ones don't. Code:

View 6 Replies View RelatedBuilding Query String - Key Value Function
Oct 12, 2010I have an issue building a query string. Basically, I have this:
/sites?order=site_numper_page=20&
But I would like to convert it to this:
/sites?order=site_num&per_page=20
I have tried this to check if the current iterator is less than the length of the object and if so, then add the "&", otherwise, don't. But it doesn't seem to work:
$.each(query_string, function(key,value){
params += key + '=' + value;
if((value + 1) != query_string.length){
params += "&";
}})
Ajax :: Cannot Pass String To Function
Aug 27, 2008I am using ajax to pass php variable to javasccript function as shown below for my particular application.
i am using the foolowing function from ajax.js freely available from net to implement the ajax functionality as

2] When $table is having a string with alphanumeric characters for eg: "123efg" we get the error report as "missing ) after argument list"
3] When $table is having a string with alphanumeric characters for eg: "efg123" or "abcdfr" we get the error report as "efg123 is not defined" or "abcdfr is not defined".
Get The Length Of String Function Not Working
Aug 16, 2010i used the String.length(string) function in javascript to get the length of string but nothing happened. It doesn't give me a value when i tried to view the result using an alert function. Actually, this kind of problem does not only exist with the length function, it's also the same with the trim(). I have not tried using other functions but perhaps it won't also work. What could be the possible reason for this?

Aug 25, 2010I am new to Javascript and i'm currently building a site that entails a 'quiz' part where the client selects an option from a radio button.

View 1 Replies View RelatedPass Object In Function Instead Of String?
Apr 28, 2011In the following example, I use the function "SetUp(SBox,AObjStr)" to send an object reference to the function "Populate(SBox,SObj)".
Seems to work OK, but it is a 2 step process to assign the JSON objects to the selected drop-down boxes. Fairly easy, but somewhat tedious, to change to fewer or more levels as desired with a common bit of code.
However, what I would like to do is simplify it a bit more ... Is there a way to bypass the "SetUp" function to "Populate" the multi-level drop downs directly? I think what I'm looking for is a way to pass a string in the function that would be recognized as an object (in this case a JSON or other form of array) and be decoded to add options to the drop-down choices, but I don't have a clue as to how that might be accomplished without the extra "SetUp" function!
Code:

<head>

JQuery :: Function To Parse Query String From URL?
Jul 5, 2009I see that jQuery provides a function to turn an object into a set of URL query parameters: $.param({foo:"xxx", bar:"yyy"}) => "foo=xxx&bar=yyy" is there a function which does the opposite, i.e.parsing a query string into an object? The reason is that when I make an Ajax request, I want to take some parameters from the original page and include them in the new request, and modify others. I can get the original page's query string from location.search, which may contain, say, "?foo=xxx&bar=yyy" Now, suppose I want to submit an Ajax request with the same value of foo as the original page but a different value of bar, what's the cleanest way to do that? Remember that the original query string might have the two parts the other way round, i.e. "?bar=yyy&foo=xxx" If I need to write a function to split this myself, I know it's not a major undertaking, but I just wanted to see if I've missed something in the API.

Function To Convert String To Ordered List
Mar 11, 2010I have a string with javascript linebreaks with /n. I want to make a function that will make a text only ordered list (text within a text area... i.e. I don't want to us ol and li)
For example,
Spot1
Spot2
Spot3
would be converted to
A) Spot 1 -
B) Spot 2 -
C) Spot 3 -
So far I think I need to use an array, and replace...
Code:
function AddLabels(element_id) {
x=document.getElementById(element_id).value;
countlinebreaksstr=x
try {
return((countlinebreaksstr.match(/[^
]*
[^
]*/gi).length));
} catch(e) {
return 0;
}
var myArray = [A,B,C,D,E,F,G,H];
var i=0;
for (i=0;i<=10;i++)
{
}
