I have a js file which will open a web site.

The argument url will be from an input field in a html file.How to implement it?
can i pass a hash as a function parameter. ive seen it been used
before but i can't figure out how to do it.
i would like to call a function like this for example
doSomething({variable1:"blabla",variable2:"blabla"});
how would function doSomething be written for this to work.
I would also like the hash to be optional and the variables in the
hash to be optional.
meaning i should also be able to call doSomething(); with no variables
in it.
I've been struggling with a piece of code. I'm guessing the solution is quite simple, but I just can't find it! [code]...
The line that I commented out was an attempt at getting a variable that had the value of the image-id, but it doesn't work.
I have a javascript will a) look for a certain value in a drop down box and b) depending on what value is selected open up a div that includes link that when moused over will pop up with an alert box contain the passed parameter. A couple problems with this, one is I am not as sharp on Javascript as I am on PHP, and two, when I manually place a value into the function parameter, if it's a number it works fine, but if its a string or word, it comes up with an undefined error. why the undefined error is coming up only on strings or words?

Can I know how to pass a variable from one function to another using parameter.
The above code seem not working.
I am trying to pass a value using a parameter in html (asp) to a javascript function. When I try to pass a value inside of a variable <INPUT type="submit" value="Next Youth" name=button1 onclick="OnButton1(tst);"> it simply doesn't work (no error msg - just nothing) while if I put a value in the call <INPUT type="submit" value="Next Youth" name=button1 onclick="OnButton1('5393');"> it works fine. The javascript looks like this:
function OnButton1(tst)
{
var pth = "youth_edit3.asp?cIndex=" + tst;
document.YouthEdit.action = pth;
document.YouthEdit.submit(); // Submit the page
}
I've set tst = "5393" but it won't work when I try to pass it. Only a literal value of '5393' works.
I currently have the following:
<a href="#" id='$dbase'>Link</a>
which passes the value of $dbase to my jQuery click function.
But I'd like to also pass a second parameter consisting of a page number. Can that be done using the click function or would I have to do it another way. I'm assuming it must be possible. I suppose i could always concatenate the two parameters, e.g. $dbase-$pagenum, pass that and then split it in the javascript but that seems a slightly inelegant way of doing it.
I'm trying to pass locally defined function as aparameter. Every time I do it, it causes an error saying something along the lines of "there is no conversion for text to function".
$(document).ready(function(){
jQuery("#confirm-ajax-submit").click(function(event){
var success = function(){
alert("this is what I want to see.");

Ok this is my first day with JQuery, so I know I'm probably asking a stupid question; But, given the following code, how do I pass a parameter when I set the function for an event.
var url = $("#deleteBlog").attr("href");
$("#deleteBlog").click(deleteBlog);
I have a dropdown named Country. ID is also Country.Now i have this function.
Function GetIndex( DropdownID )
{
var i = 5;
var value = $('#DropdownID option:eq(' + i + ')').val(); // doesnot work
[code]...
only this is working when i am directly writing the id of the dropdown like this.var value = $('#Country option:eq(' + i + ')').val(); // this works i am not able to pass the id to the function.neither can i store it in any variable and use the variable in the expression. i tried writing the id inside { }. dint work.
I want to pass Array or Object as parameter in function But can't, Here is my code

i wish to remove a table row on click i do know that it can be done using the following code
$
(
'#myTable tr'
).
click
[Code]...
what if i also wanted to pass a certain value as a parameter to this function. basically what i wanna do is, i have a 'x' on each row so when a user clicks it i want the row to delete and at the same time wish to use ajax and delete thatrow from the database as well.
I have just started learning JQuery and have a doubt in the below code. $.get('myhtmlpage.html', myCallBack);The doubt is should the 1st parameter of the get function be a HTML file or can it be a unction name?
View 1 Replies View RelatedCaptions for the images are called from the parameters of the main function and delivered into a span or div tag with the appropriate id. A very important part of what needs to be in the captions is text compiled by a separate function, in the project library.I've tried this with and without curly, square and round brackets, with and without semicolons and quotes- all with varying results. Sometimes the function is called, but it appears at the very top of the page and nowhere near the proper <span> tag.
addImage(a,b,c,d);
// filename, image name and caption are in a, b and c.
// d is the variable where I need to write my other function...
addRef(t,s);
// I need to put addRef in the d parameter of addImage.

I am trying to minimize the amount of script that I use on my website. I have sections of each page; each section has the same basic layout. The divs and images that I want to make appear and disappear all have nearly identical ids, the only difference is the number at the end of the id.Is there a way to get one script to automatically detect which id number has been clicked and then show all elements with the same number at the end of the id? I would also like it to hide the elements in the hide function below (basically they are the elements that do not share the same id number).I currently have everything working the way I want it to using multiple functions like the one below but I woul
$("#2thumbNail2 , #ledBar").click(function () {
$("#type201 , #type203 , #type204").hide();
$("#image201 , #image203 , #image204").fadeOut("slow");

I am trying to use a regEx to grab Function names and function parameter names from a text entry.
The script is written in javascript and I expect the functions to be in javascript syntax.
For example the code might look like:
Code:
function myFunction1(param1,param2,param3){
some code
}
function myFunction2();
function myFunction3(param);
Whats the best way to accomplish grabbing the function names and parameters?
Should I be breaking it down into multiple regular expressions?

I have a simple JS function that I want to return a true or false value
based on the parameter passed in. At this point of time I receive the
error "'True' is undefined". Here is my code below.
JS Function -
function ShowSpecifiedPeriod(pShowPeriod){
document.mfperformance.ShowPeriod.value = pShowPeriod
document.mfperformance.method = 'get'
document.mfperformance.action = 'composite_requestdata.asp'
document.mfperformance.submit();
}
ASP Event Handler -
onclick="ShowSpecifiedPeriod(<%If bShowPeriod = false then
Response.Write true else Response.Write false%>)"
The ASP variable bShowPeriod is set based on the hidden form field
"ShowPeriod" and the initial value is set to false.
More than likely this has to do with the boolean Parameter but I am not
sure how to handle this in JS. I have tried the following but receive
the same results.
function ShowSpecifiedPeriod(boolean pShowPeriod) - Same Error
function ShowSpecifiedPeriod(pShowPeriod boolean) - Same Error
Please let me know what I am doing wrong here.
Is is possible to set a variable name from a function parameter?
Kind of like this but it doesn't work!
I have a JSON array data.cells that I need to iterate through to get the values out of and put the values into an onclick event listener.
Right now the variable name data.cells[i].letter is being based through the buildString function for each cell in my board, instead of the value of the variable. Same goes for the x and y variables.
I've been searching now for quite a while trying to look for a way to give the default value to a function argument if it's not given. For example, in php one would do the follow:
function func_name(foo = 'default') {
...
}
In the above case, if foo isn't supplied while calling for the function, then foo would default to 'default'. I have tried that in javascript, but it doesn't appear to be working, so I am wondering how should I do this in javascript?
