Jquery :: Functions To Work When Certain Elements Or Identifiers Are Present On A Page?
Jan 8, 2009
I have a single javascript file that contains all of my javascript functions. Each of the these functions are particular to different pages on my entire site. How can I create logic that will only allow those functions to work when certain elements or identifiers are present on a page?
I have a page that inserts a div after another div on my page. Basically this div and its content are generated by the server and outputted via Ajax when the user clicks a button.I have something like:
//Listener function $("div").click( function () { alert("thing"); });
Clicking any of the divs that were loaded on the page will give this alert however, clicking on this div that was inserted after the user clicks a button does not respond to this listener. I put my rendered html into the w3c validator and my page has no errors (because I thought that maybe I had a missing end tag which would cause jquery to not work).
My goal: I'm trying to to create a configuration dialog and persist it so the user can edit it later. Since the configuration is long and has Datepickers, Sliders, different types of inputs and such, I'm loading a new page for the configuration and using ID to get values from them. For example, the page has a datepicker text input "startDate" and a datepicker for it.My problem:1) I load theconfigurationpage into a div of home page make a dialog out of it. jQeury moves that div to it's own div that it created in the body of home page. So when I add multiple dialogs, datepicker doesn't work anymore since there are two "#starDate" input fields in the page now. I also plenty of other cases where I use the ID directly to do other tasks. Is there a way for me to go forward with this.
our requirement is client wants to know howmany users leaving the main page without entering data in the application page.at that time we need to show the css popup overlay.in the following scenarios overlay should pop up.1)when user leaves the page.(e.g. type other address in the address bar).bascially user shy away from the browser.2)clicks browser close button.we will show one css popup overlay(not browser popup) and in the back ground main application will be greyed out.this overlay consists of some text fields and some buttons will be there and parallely in the back ground we will execute AJAX call.can we accomplish this requirement??is yes how?will it work in all browsers?my concern is how to prevent the browser from closing when css overlay comes up?

Here as there is no link specified it will open a blank page. guys can u please tell me how can i write a condition so that if my href is blank then it will not open any page. the click should not work or else it should load the same page.
within this page that has been created, there is an AJAX tree folder which calls another page to be loaded into a DIV by AJAX again. Code:
[Code]...
I don't know why it doesn't work because the page has been loaded with the JS file, but as soon as the link is added afterwards it doesn't work. I take it this is because it doesn't know where to find the JS, but how can I overcome this?
I am currently trying to use Javascript to dynamically resize a navigation div (that is present on every page) according to the size of the main content div.
I am currently using the following code;
Code:
This works the first time I go to the site and if I refresh a page. However, if I use my on site navigation to switch between pages the div simply uses the height variable defined within my CSS (this needs to be here for users with JS disabled)
Does anybody have any ideas on what the problem might be. It's as if the script is only executed the first time any page on the site is loaded, but then not again.
I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. :confused:
The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing.
function testWrapper() { function frequencyWrapperOne() {
Im initiate with jQuery now and trying to create some elements and, after that, create functions for this. What i do is:
[Code]...
function" works fine, but when i try to execute the "close function" i cant get he result. Its seems like after create element, i cannot use any action with jquery for. I know, probably this is very simple, but i need to practice step by step.
I have a table that i load into the document via ajax. the table shows a list of times. every row has a button that when clicked should call another AJAX function. However when clicking the link nothing happens. If I put a link in the original document myself and ask it to do this, it works fine, but becuse this is generated code, this option will not do.
I cant get my cookie to work. I believe its not my javascript that is wrong. Can anyone take a look to see what i did wrong in my cookie? I have to pages dropdown1.html and dropdown2.html. Both pages have the same exact dropdown list. There is also a javascript file called script.js which makes it so you get an error if you select the same option on the second drop down list as the first. Also in the script.js i have a cookie that should run so dropdown2.html should now what was selected in dropdown1.html Can anyone see if i made a mistake in either my javascript code in my cookie? Right now I am not getting the error message if you select the same option as the first. Ill show all my code incase you need it for reference
dropdown1.html
Code:
Code:
Script.js (this is the part where I cant figure out why the error message does not appear on the second dropdown menu if user selects the same option as the first)
I'm pretty new to jquery and I've been working on a little project to see what I can do. The issue is when I first visit the page and click the first link that appears in the main section it displays the popup box as wanted. Now when I click another day, for instance sunday and try to click the first link it doesn't do anything. And if I click back to Saturday the first link also doesn't do anything.
It seems something is not properly activating or maybe a command is overwriting and not allowing it to work like it does when you first hit the landing page.
I have a slideshow using jQuery and just added an apple overlay to the same page, and for some reason, now the slideshow will not work..Here are the links I have..:
I wondered if two jQuery functions work at the same time on the web page. I did practice one with two jQuery functions, just one function work while other isn't. What is causing it? What should I do to prevent having one is working while others isn't ? Is there a code to put in there to prevent it? If so, where should it be at?
I have a simple problem and cant seem to figure it out. I have a function in the body.load function that is supposed to highlight rows in my table when i mouse over them. When u refresh the page, the function works properly. When I dynamically add new rows to the table using ajax, I get no response.
When creating a new element by using HTML string, we can define a function inline so that we don't have to write another line of javscript code to bind the function to the element. It is very convenient.
The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.
No syntax errors - nothing should be getting in the way of this. All I'm trying to do is implement a different an "onclick" call, which calls the function and AJAXes in some values. Here's my code:
I have a series of elements on the page that have been assigned anonymous functions as a user works with them. At a certain point I would like to take a element and all of its children and copy them from their current location and into a newly created element. Then remove original version and all its children.
I have done the above by using innerHTML to copy the element and its children to a temp variable.. problem is that I think my copy has lost all these anonymous function that was assigned to the original version. Has anyone ever faces the problem of trying to copy a series of elements and losing their anonymous assigned functions in the copied version? If so whats the work around on this?
Im trying to add a cross browser event listener to an element so i made my own function that detects weather the browser is IE or Firefox, then add the appropriate eventListener function to the element.
Code JavaScript: // CROSS-BROWSER ADD EVENT HELPER METHODS function addCrossBrowserEventListener (elementName, eventName, functionName) { // does the addEventListener function exist?
[Code]....
but when i run the code inside Firefox i get a error message "name.addCrossBrowserEventListener is not a function".
So I'm wondering is it possible to add custom functions to elements directly or is there any special way of doing it.
I'm trying to make a web page using javascript for validation, but after the last 2 functions I wrote, 2 functions don't work anymore. I attached the file so you can see for yourself. And I know there are a few things I could do to the html, but I'm saving those for last. why the scripts don't work .(the functions that don't work are: "cont_pag1" and "cont_pag2"...btw...they worked just fine until I wrote the last few functions (the ones for the pag4 div)).
I am trying to include two functions in an onchange when the user selects a new value from a select list: It is a quite big form form - There are one select list, when changed - TWO other fields in the form needs to change accordingly: I put the information back using ajax and place it within a <span id="blah"></span>; I have checked the span ids, and they are correct! Unfortunately, the second function disables the first one This is the select list with the onchange functions:
