JQuery :: Adding An Event Handler To A String From A $.post Reponse?
Dec 6, 2011
I have a basic HTML form with a button that submits the form via jQuery's $.post to a processor. That processor returns the identical form, including any errors below any of the elements e.g. input, textarea, etc. The response also has a new submit button to submit the form once more, however, because I'm retrieving a giant string with HTML elements and because jQuery already loaded, that new submit button doesn't do anything. How can I parse jQuery's response for that button and assign a handler so that when the button is pushed, it submits the form again?
Normally, when I use .post in an event handler, "this" refers to the object that triggered the event. That doesn't happen in this case. When I use "this" the first time, to pull data parameters, it refers to the .trigger_button. But inside the .post callback, it refers to the AJAX call object instead. I don't think that's how it's supposed to work, is it? Is this a bug?
I have a <div> containing 3 buttons. The buttons have id's like this: Button 1: btnFoo Button 2: btnBar Button 3: btnBaz
I'd like to add an click event to each button to call a function named [button ID]_click(): i.e. btnFoo_click() btnBar_click() btnBaz_click()
So far I have this: $("#divButtons button").each(function() {. $( this ).bind("click",function(){ eval(($(this)[0].id) + '_click()'); }); }); This works but is there a way without having to use eval and still utilizing the lovely .each function?
I need to know how to add an event to a button. The specific issue is that I want to add an event which is a prototype function of a class. Consider the following as an example:
I have a TabContainer on my page, and I want to add a keyup handler to the textbox, but somehow I counldn't find the textbox in my jquery function using $('#TabContainer1_TabPanel1_TextBox1'). Here is my code:
Im trying to develop an AJAX application which updates a <select> list with a series of <option> tags when the user makes an entry in a field.
Therefore, my ajax application needs to dynamically create <option> tags and append them to the <select> list on the form. I have got this working in all browsers. However, i do not know how to add an "onclick" event handler to each <option> tag that is dynamically created in my javascript code.
Code:
As you can see, i create an option javascript object for each new <option> tag and add it to the <select> list. This works. But how can i also add an "onclick" event handler in the javascript code?
What is the evaluation context of the setTimeout args below? I have a separate Timer instance for each sprite in my program. As coded, "this.Clock" doesn't work.
Don't you see that the whole aim of Newspeak is to narrow the range of thought? In the end we shall make thoughtcrime literally impossible, because there will be no words in which to express it.
I've many div with sequence of ids like d1 d2 d3 ... and I need to listen to their click event so I'm using a loop to add an event handler to them, Here it's my code:
for(var i = 0; i < $ds.length; i++){ var $d = $ds[i]; var xFunc = function(e){ document.title = "d: "+$d;
[Code]....
But when I click on each of them always the title goes to "d: 4" where 4 is the last value in $ds.
I'm creating a drop down menu so that when a user clicks on the drop down arrow and then hovers over one of the options, a bubble comes up and does a validation. The thing is that everything works fine in Firefox, but not in IE or Chrome. The problem is that the .mouseover() function doesn't work on the <option> tags in IE and Chrome, but it works fine in Firefox because apparently FF is the only browser that supports it.
I'm trying to change a word in an animated collapsible div script from Dynamic Drive. When clicking "Hide" I want the word to change to "Show". I have part of the script, but it's not working correctly - it just removes "Hide" when clicking on it. See the example here.
The code so far is this:animatedcollapse.ontoggle=function($, divobj, state){ //fires each time a DIV is expanded/contracted //$: Access to jQuery //divobj: DOM reference to DIV being expanded/ collapsed. Use "divobj.id" to get its ID //state: "block" or "none", depending on state if ($('#'+divobj.id+'-toggle').length==1){ //if toggle link has id 'divid-toggle' defined if (state=="block") $('#'+divobj.id+'-toggle').prepend('<span class="prefix">Hide </span>') else $('#'+divobj.id+'-toggle').find('span.prefix').remove() }} I'm totally new to jQuery.
My plan is to create a JavaScript class, with some functions and variables, and one of the functions is called when a user clicks on a certain element. However, I need to find out the ID of the element that was clicked (in the example, that of the <p>) for further processing. It looks basically like the following:
[Code]...
The result was very crazy, because console.log(this) gave me the node as result, and console.log($(this)) did the same only as jQuery node, but trying to find out the attribute via jQuery gave undefined as result. I haven't checked if this.id would work (should probably), but I'd prefer to keep the whole script in jQuery, if possible. I suspect it may be an overusage of the 'this' keyword, but if so, what's the proper way to do it?
i'm looking for the best way to use global properties that defined at class level insid event handler functions.
for example : function MyClass() { this.v1 = "hello"; this.v2 = {name: 'joe', age:'30'}; this.link1 = $("<a/>", {id: "link1"});
[Code].....
actually, in link1Handler 'this' returns to link1 not to main class. so how to get class properties or functions inside the private functions of the same class?
I haven't come across an exampe that would enable me to pass data to my event handler.For example, if I click a button I want it to pass the value of an adjacent text input to my handler.
I've a very simple code where i am setting the font-size to currect font-size + 2 for a paragraph. Its set first time but when next time event handler is called it gets the same old value.code is ...
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head>
In the below code snippet I'm trying to add an dynamic event in <div id="button3"> when you click at button1, which is added static in the html body. button3 has exactly the same behaviour as button1, but the eventhandler will not be activated.
I am have an MVC app that generates a list of rows, of which one of the columns is a button. Here is the rendered HTML for the buttons: <input id ="btnUpdate21" type ="submit" value ="Approve" synchId ="21" /> <input id ="btnUpdate22" type ="submit" value ="Approve" synchId ="22" /> .....
Following is my selector that I use to bind the buttons to my click event: <script type ="text/javascript" charset ="utf-8" > $(document).ready(function () { $('input[id^="btnUpdate"]' ).click(promptForSynchDate); });
I have been trying to access the button Id, though what I really need is the attribute synchId, to use inside of a modal. I have so far been unable to access either one of them. My modal works fine. But the value of either attribute is always "undefined".
Here is my click event handler: (I stuck the alert in there just for debug purposes) function promptForSynchDate() { $(document).ready( function () { var test1 = $(this).attr('id'); alert( 'test1 is : ' + test1); $( '#approve-synch').dialog({ .....
So I have an event handler for the KeyDown event in a Javascript file but for some reason it does not get called the first time a key is pressed. However, if a key is pressed or a mouse button clicked then the next time I press a key it does get called. Here is the relevant code:
........................... // Other stuff $(function()
Its a very convoluted title, but not sure how to phrase it.I'm using the latest version of jquery. i have a function that creates a new row given an onchange event for the primary select box. This new row contains another drop down box that i want to bind another onchange event. Problem is when the child drop down change event is triggered, if there are multiple children, the alert pops up for the number of children that it has.. horrible explanation heres the code:
Code: $('#perph_type').change(onSelectChange); function onSelectChange(){
it's possible to bind a function to an element that is fired if that element is 'moved'/repositioned via the browser.
For a more specific example what I have is a function that calculates height and width of certain elements to allow them to all fit nicely on the page without having scroll bars, and this is bound to the window onresize event. It works nicely most of the time but occasionally something will change the height of one of the elements and this effectively bumps one element right off the page.
So I'm wondering if its possible to have an event bound to an element that is fired when an elements position is moved/recalculated by the browser? Short of polling every second or so, to see if it has moved/recalculate layout.

[Code].....
When I open page2.html, and click on the brnClick link, it changes the content of divclick. If I open page1.html, and then navigate to page2.html, click on the link does not work.
On the very next line I am attempting to bind a submit event handler to the form:
$('#loginform').submit(function() { $.post('member.php', $(this).serialize(), function(data, status) { data = eval('(' + data + ')'); if (data.msg) {
[Code].....
The form is loading fine, but for some reason the submit() is not getting attached to the form. Therefore when I submit it is running member.php from the form "action". Ultimately, I want to be able to run member.php from $.post() so that I can tell member.php that JavaScript is enabled.
