JQuery :: Apply Validations On Dynamically Generated Forms?
Jul 7, 2009
I am using the JQuery validation plug in for form validations. My page contains a loop in which dynamic forms are generated and within each form some text fields are also dynamically generated. I have assigned the id and name attributes both to form and fields with dynamically appending a value. Now I want to apply the validation on all these form, please note that each form contains its own submit button. I have tried using the following selector,
I am rather new to JQuery and would like to use it with php. I ran into problems when my html is not static, I generate php forms on the fly using my php script and JQuery just doesn't seem to validate those forms. When put the same form in static html file JQuery works like a charm. What could be wrong? Does JQuery need a page to be static? Right after I load my php page firebug reports that $(document).ready(function() { is not a function and JQuery is not defined. I have loaded the necessary JQuery libraries.
At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code: var tbody = document.getElementById('tableItems');
var td1 = document.createElement("td"); td1.appendChild(document.createTextNode(qty)); td1.setAttribute("class","qty"); row.appendChild(td1); tbody.appendChild(row); One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?
I have a database that shows about 5 to 10 recorrds on a page that contain forms for the user to fill out. The number of rows is unknown and depends on the user query.On the page there can be 2 or 10 records displayed ..each containing a form that needs to be validated.How can i use that. The IDs of the elements would have to be generated dynamicly i suppose. Anyone of you got an idea how to do that ?
I'm trying to update a plugin i downloaded. What i'm trying to do, is make it able to work with dinamically created objects. I'm using the live function to assing javascript events, but i need to know how to assing a plugin dynamically. This is what i have right now:
$("#txtinstruments").AutoComplete("query"); What this does is apply the AutoComplete plugin, to all the objects with id txtInstruments that are already created but, i create more objects with that id on the fly, and i need to assign the plugin to them.
I'm stumped on a jQuery related development task. I'm using jQuery in a SharePoint Web Part...The web part pulls data from a list and displays each item as a link button. When the link button is clicked it uses the jQuery-UI to display the body of the list item in a dialog box. I have this working perfectly when all of the class names are hardcoded. So in this code dialog0 is the class name for the body of the first article. newTitle0 is the linkbutton so they correspond 1:1 (and so on Dialog1, newsTitle1 etc..)
Problem is, when I have more than 1 instance of the web part on a page, because they use the same class names (2nd web part would also use Dialog0, newTitle0), if I click on an item in one web part, the item with the same class name opens in the other web part as well.
I've implemented it so each item now has a unique ID but I don't know where to go from here, so multiple instances of the web part can be on the page, and have the jQuery know which body to display when a link is clicked.
I have succesfully applied the datepicker to a blank textbox. However, when I apply the datepicker to a textbox with the initial value dynamically set to display a value from a database, the date picker genertes an error when anything on it is selected. The datepicker will display when the trigger icon is selected but you cannot select anything from the date picker without generating the following errors: When selecting:
a day: 'undefined' is null or not an object (ui.datepicker.js line 767) a month or year: 'input' is null or not an object (ui.datepicker.js line 755) a back or forward arrow: 'settings' is null or not an object (u.i datepicker.js line 1137) I have looked at these lines in the file, but I have no idea where to begin.
I have a jsp file that is used to display data from Java objects running on my server. I'm using JQuery for tabs and to handle the ajax calls to a servlet that affects the Java server I have running.Each tab represents a service, and has a corresponding java object on the server side. These are generated from the spring configuration, and is working fine. The page is used to control some aspects of the service, and I have a few buttons that can be clicked. I'm trying to get it so that when a button is pressed, the appropriate Java function is called on the service's object (this happens using ajax) and then refresh the current tab.
My js code is like this:
function doPause(params) { //some additional params set doAjax(params);
[code]....
Right now, I'm using the window.location.reload(true) to refresh the whole page but I'd like to just redo the div for the tab that contains the button that has been clicked.I have tried:
There can be any number of 'groups' but I would want to apply some validation for each item in a group. I can only see that the validation is done by specifying a id? however as the id's are going to be dynamically created how can I do this? can you validate for a css class?
I am trying to write a Greasemonkey script using jQuery to automate various processes on a web site. One of them involves automatically filling in a form located in a dynamically generated iframe. When the frame is generated I can do $('#NewFrame').length and get 1 confirming it is now available. However, when I do $('#NewFrame #TheForm').length I always get 0 even though I can clearly see the form there in the iframe.
I’d like to inject the following Chicago image [URL] into the 3rd position of my list. My list is being dynamically generated using getJSON, and pulls from the flickr API. How do I accomplish injecting this image into the third position? Here is a link to my work: [URL]
I'd like to do something like this: After the page is loaded I have some forms with submit buttons. The buttons have a class called "open". By clicking any of these buttons the script is using AJAX to take some data from database and add some HTML to the document. This part of generated HTML has also buttons with a class "open". By clicking any of the new buttons script should do what it does with the old ones. The problem is I have no idea how to "refresh" a click function. After generating HTML it "sees" only the old buttons.
Here's some code:
$(document).ready(function(){ $(".open").click(function(){ var idVal = $(this).parent().parent().find("#PlaceId").val(); if($("#admin_places_"+idVal).html()=='')
I've got a form that dynamically generates sets of input elements. First there is a set of up to 99 parent elements, and then the parents can have up to 99 child elements each. My question is not about the generation, but about capturing the data once the form has been filled out.
I made a script that handles getting the values and putting the values, along with their input id in an object that is used later. I don't want to have to use css classes or other attributes to identify the input elements, and wondering if that being the case, if I could get a critique of my script:

The output (the object) logs to your console when you click anywhere in the Result area.
From WebForm1.aspx, I have successfully retrieved a string that is dynamically generated in WebForm2.aspx and spit out to a Literal control in a div. This is what I did.
That's pretty simple and easy to understand for you jQuery gurus out there.
Now, I am trying to do the same thing within the single web form. That is, in WebForm1.aspx, I have this jQuery script to post to the same web form (i.e., WebForm1.aspx), but it is not working. Postback works OK, but I am not able to retrieve the dynamically generated string and spit it out to mydiv.
What's the jQuery way to do this? Any example? I searched, but I've only found examples which try to get static string values, which I know how to do.
I'm making an ajax call to my server and then, with the information I get back,ynamically creating HTML with jQuery, then appending it to my desired div. This part works excellently. The issue I'm having trouble with is I'm only returning five records, so I'm creating a span at the bottom labeled "see all", but even if I give that span a class,it's clearly not registering in the DOM because when I click it, my jQuery code doesn't even know it's there.My question: How do I get those dynamically generated elements to register in my DOM so they can be called by a jQuery click event?I realize that I can just do an inline javascript call to my function and that works fine(ish). The problem is, however, I want specific information about the particular span that I click, and if I call it inline, it doesn't send $(this) to my function... it recognizes $(this) as $(window), not as $(span that I clicked)
I'm having some trouble with my dynamically generated form fields.
As you can see I'm generating new form fields, but the problem lies within the grade field. I have it set up now so that when you change the grade the color of the <select> box changes relative to the grade. A-D are green, F is black with white text, Not Taken is just regular white with black text and In Progress is lightly shaded grey.
I want it so that each one can be changed individually, but I can't seem to be able to figure out how to do that. Heck if you change the first one's grade field, that colour follows the rest of the clones.
This is the jQuery I'm using to change the color of the thing.
I am new to jquery but i have figured out how to link datepicker to a dynamically generated tablethis funtion works but only posts the date to my ajax call (Array ( [date] => 04/01/2009 ) for example)I need for it to post the id of the original input which i than can derive the actual id of the mysql file so i can update the correct date ( for example id = "picker_2343", the attached number would actually be the file id )so how can i include in $_POST the original input id or class id ??, $_GET could work also....
I want to dynamically generate list box options using the content of an sql database in real time. More specifically, i have a page with a couple of listboxes, when i click on an option in the first list box, i want the second list box to update with options that reflect the first one, in real time generated by the sql database.now i was wondering if it might be possible for javascript to send some thing to php which php could decode and search the database and return the results of that search. here is how i imagine the process to look in psudeo code:- user clicks on an option (say the 3rd option) in the 1st listbox- javascript catches the event, and sends some data to php indicating the 3rd option from the 1st listbox has been clicked- php tells sql to search for records that correlate with the 3rd option from listbox 1- php sends search result back to javascript- javascript populates the 2nd listbox with search resultsi want to do this with out having to refresh the webpage, security issues aint high, cause this project probably aint gonna go on the web. I got the idea from the dynamic searching on google, so i guess such technology is possible some how.
When I add a tab, whose content is a form. The form is loaded by ajax $.ajax('url'); On ajax complete, I add a custom method for validation, which is supposed to get called when the "Upload" button in the form is clicked, but it never get called. I have searched and tried multiple things for two days now, and nothing works.
I'm having a problem with the page at http://www.bathfringe.co.uk/contributors2011_2.php The user is able to add new performances to the form. This functionality is provided by cloning elementsPart of the code should add a 'counter' array key to the names of the cloned form inputs (full code obviously available at the page linked above):
function selectDefaults(buttonGroup){ for (i=0; i < buttonGroup.length; i++) {
if (buttonGroup[i].checked == true) { for (count=1;count < document.addForm.recordCount.value; count++) { var doc = document.addForm.feature1[i] var featureVal = doc.value; featureVal = featureVal.substring(0,2); if ( featureVal == "SF"){ doc.checked = true} } }}}
I need help in the second 'for' loop. Currently it is hard coded to replace the value of document.addForm.feature1 - but this field name is dynamically generated via the page it resides within. That being said, its name/id will increment depending on how large the recordset is. i.e. feature2, feature3, feature4 etc....
How do I get this to work in the javascript? I need to use this script to search all the 'feature#' fields in the form when the script is triggered. All I could think of was this: var doc = document.addForm.feature+count+[i] which gives me a syntax error.
The purpose of this script, for those who will wish to know, is to automatically select all the features of the product that have the text "SF" (standard feature) in their value.
I cant seem to get the reference to the 'header' IFrame that is dynamically created. I can reference one called 'footer' that is created in the same line of code as the other IFrames however (oddly enough). I've tried numerous ways with no luck. Since this is inherited code and designed years ago to run on IE only it's a mess. You'll see I've tried alerting out various different ways and simply left it in to show my feabile attempts.
Code: function mit(e) { var iframeElement = document.getElementById('header');
And I doing some validation like this. function checkvalue() { var f = document.forms['formA']; var eLen = f.elements.length; for (var i=0; i<eLen; i++) { if(f.elements[i].name == "text_" + i) { alert ( f.elements[i].name); } else { alert (f.elements[i].name); } }
It never goes into first part of if statement.. Is there a way I can access these kind form elements..
