I'm trying to extract a value from an attribute, namely listid in this case, inside an input tag.code...
$list is an associative array fetched from a database. The contents of that array might be irrelevant for the issue. I'm using a jQuery to handle any javascript code. How do I extract $list['id'] from this input tag?
or is there another genius way to accomplish the same other than using an input tag?
I like to ask about how do I get a partial attribute value? My code:
<a href="#" id="id-1">Link 1</a> <a href="#" id="id-2">Link 2</a> <a href="#" id="id-3">Link 3</a> I like to extract link attribute value in id-x, so I'll get numeric 1 or 2 or 3.
I have quite a few calls on my page at different points to populate dropdowns using jSon responses from the server. It is all working fine now apart from one issue. The name of the field that sets the value and text of the new Option(s) being put into the dropdown.
i have found a possible bug in 1.4 but it's only in Internet Explorer 7 & 8.The following code does not work and completely ruins every peice of jquery on the page (that means everything inside $(document).ready and anyting else...
I cant see any syntax errors - i pulled the example from the 1.4 site. There is no trailing commas in the object notation and i really cant see any reason it would work in firefox and not IEx and more to the point not only not work in IEx but break any other jquery in the entire page....
I'm working with a large (and unweildy) ASP.NET application, and there is a lot of jQuery code that uses selectors like this:
[name=_aspnetControl$_withASubControl] And unfortunately, some selectors that also look like this:
[name^=_someAspNetControl$_radioButtonList].
In other words, the effort to remove the $ from the attribute selectors would be monumental. If it is possible to escape the $ symbols, I can do that easily enough, but unfortunately the situation right now means that I can't upgrade to jQuery 1.5.
I'm learning jQuery with XML. I'm familiar with other query languages such as XPath. I'm having a little bit of difficulty wrapping my brain around how jQuery works but I think I can make the leap if I see a solution to a problem I know how to solve with other methods Given the following XML, please share a jQuery solution to finding the value of attribute B in elements named bar where attribute A has the value 30:
I have 40 or 50 inputs scattered among many pages that all need the ability to open a popup which allows the user to navigate a file directory structure, locate a specific file, and return the fully qualified file name to the parent window input. All the 40 or 50 inputs have unique IDs. Given any one input ID, I have everything working perfectly: the parent form opens the popup using window.open("FileFinder.aspx?dir=" + UserRootDirectory + "&InPutID=" + IdCodeInOnClick);
Popup talks back to parent using window.opener.document...
Like I said, give me the input field ID and I can make everything work every time... but it makes NO sense to write 40 or 50 functions, one for each unique input field. I tried using
but I keep getting an error message about something requiring an object. Is there a way to accomplish this? Also, since I'm new to JavaScript (and web programming generally), is there a good tool for debugging JavaScript intended for IE?
I am looking for a generic form validation script for my personal project. I found few out there in search but nothing too close to what I want.
If I have a form in a page I want to call the javascript valdiation routine and display all elements error messages in one validation to their parentNode.
I found few routines which displays error message in alerts and that too validation for one element at a time.
Can any one point me to open source generic form validations.
I'm trying to write a generic/reusable form validator in Javascript... just something that checks to make sure required fields have a value. By generic I mean I don't want to explicitly reference the name/id of the form or the name of any of the data fields within a "validation" function.
if(problemFields.length > 0) { returnval = false; warn(problemFields); /* tells user they're missing a field, that's all */ }
return returnval; }
What I think is happening (not sure) is that the expression form[fieldsToValidate[i]] is not giving me what I want: a reference to the object corresponding to the form field with the same name. In otherwords, I must have some fundamental misunderstanding of how the DOM works here. Unfortunately, I can't seem to find a good enough reference to set me straight....
My page has a form comprised of several radio buttons. I want to poll the buttons to determine which button was selected and convert its value to a string. I then want to use the string on the same page. Code:
ok i have a script which will make a copy of the html in a div and place it into another div the problem with this it creates a duplicate element with the same id so what i want to know is can i create a new id based off old ids using a generic type script
function scope(e) { var popin = document.getElementById('popin');
I want to write a generic clearForm function to clear the form when the user click CLEAR button.
Here's my attempts, because I want to take care all html controls. I think I need to test if the control is submit button, regular button. But I don't know what I should do on drop down box?
function clearForm() {var i=0; for (i=0; i<InputForm.elements.length-1; i++) {var obj = InputForm.elements[i]; document.write(obj.type); //runtime error: object doesn't support this property or method if (obj.type != "submit" && obj.type != "button") obj.value = ""; }}
I want to learn more about creating functions for element events without having to put onclick event in every tag. For example:
<script> document.getElementsByTagName('input').onclick = function () { alert('hello'); } </script>
Now, I know the above does not work as I have tried it but hopefully the idea of what I am trying to achieve here. Basically for every input tag, when the user triggers the event (click) it will do the same function.
Anyway, I would more so like to learn about this type of scripting where you assign functions to events. However, I dont know what to search for in google and the like. Where could I learn more about this?
I'll trying to tell the difference between the following three cases:
<img alt="text string" /> <img alt="" /> <img />
I can do this in Firefox with the following code, where elem is the HTMLElement representing each image, but IE doesn't seem to differentiate between empty string and undefined.
var alt = elem.getAttribute('alt'); alt = (alt) ? alt : ((alt===null) ? 'really_null' : "");
The desired output from running this code on the 3 tags above is:
text string
really_null
It seems like this should be really easy...but I'm having a really difficult time trying to figure out what's going on...
I need to extract some data from the following block:<span <aref="localhost:80/items/2">item link</a> <span>item attribute</span></span> I can get the item link anditem attributedata by using $("span a") and$("span span"). I, however, can't figure out how to extract the "2" from the "localhost:80/items/2".
to append a parameter string like: '?key=val' to the currenturl and the value for the key changes based on the user input. Isthere any jquery utility that does the base url extraction fromwindow.location, so that I can append the '?key=val' to that?
I need to get the innerHtml details of a page .in the below script when i alert the obj iam getting the Text of Html i need to get the inner html object how it is possible.[code]...
I have this JSON file that does the encoding from the states database.I want to extract it out using jquery and populate the select dropdown box. the json file is being encoded in this way:
[ {"State":{"name":"AUSTRALIA CAPITAL TERRITORY"}}, {"State":{"name":"NEW SOUTH WALES"}},
To manipulate strings, but forexample when Iam programming an event with jquery and extract data from a textfield for example I can,t do this var msg=msg.subtring(0,5);
I stumbled across jQuery while during a search for my project that involves parsing and extracting content from HTML pages. I have a collection of xpath strings that identifies the data I would like to extract. Wondering if I could use jQuery for this purpose.
