I have a page working perfectly that passes up to 10-12k worth of data into a function via an 'onClick' event. That onClick is one of the <img..>'s attributes, directly. In case later that (dynamic) data gets larger, am I toying with potential problams because of some limit - either a limit in what can be passed into a JS function, or else a limit in the max num of characters allowed in an element's attribute(s)? What do you think is the reasonable amount that I can pass before things start to break? I may need to go up to 50k. 100k maybe, but I doubt that much.
I'm experienceing some problems with jQuery 1.4(.1) with the "new" ajax param serialization. My code does basically this:
[Code]....
so I'm creating an array within the "ajaxparams" object, which I fill with some data. So far so good. Problem here is, the $.post request creates a string like this:
[Code]...
Release Notes Snippet: jQuery 1.4 adds support for nested param serialization in jQuery.param, using the approach popularized by PHP, and supported by Ruby on Rails. For instance, {foo: ["bar", "baz"]} will be serialized as “foo[]=bar&foo[]=baz”. since I'm working with perl and not php, this issue is getting a little bit annoying.
I have a Javascript which is to count the number of characters entered into a Textarea box and to prevent any more characters from being added after a certain number has been reached. Here is the code:
I am trying to adapt a script for use validating a drop-down menu in a form.
The script works fine in my lttle demo. In the head of the page I've got...
Code: <script type="text/javascript"> function checkList() { var testForm = document.testForm; if (testForm.demoSelect[testForm.demoSelect.selectedIndex].value == "") { alert("Please make a valid selection from the list."); return false; } } </script> And then in the body...
HTML Code: <form action="demo.php" method="post" name="testForm" id="testForm" onSubmit="return checkList();"> <p> demo select menu <select name="demoSelect" id="demoSelect"> <option value="" selected>Please Select</option> <option value="1">Attrib1</option> <option value="2">Attrib2</option> <option value="3">Attrib3</option> </select> </p> <p>Submit <input type="submit" name="Submit" value="Submit"> </p> </form> No problem, works fine. The problem is that I am trying to apply this code to a PHP page in osCommerce where the name of the drop-down menu (i.e. demoSelect) is generated dynamically. It is only for use in one particular situation where I know the name of the drop-down menu is generated as id[1] but it wont work when I replace the demoSelect for id[1].
I'm only really beginner with JS but I guess it's because JavaScript identifies id[1] as an array? Is this right and any ideas how I can correctly identify my drop-down to JS?
I am trying to use a method equalTo from jquery.validate.js and could not find how to use the "param" parameter. Below is part of the js file I am referring to: Code: // [URL] equalTo: function(value, element, param) { return value == $(param).val(); },
I want to split the result from window.frames['data_frame'].document.location;, this in order to find out which page is currently opened in the specific frame. When I do it like this:
var source = window.frames['data_frame'].document.location; // var source = "W3Schools is great!"; index_source = source.split('/');
IE gives an error that this method or property is not supported by this object. When I check it on the other var it is accepted. Is there anyway I can make this work? I already tried to do it with document.getElementById().src etc.. but that is not very reliable.
I have created a javascript for form validation. But I want to add some more functions in it. Like it should allow only US zipcodes. Phone Number will be in Number format only. I referred many other sites as well. But its getting difficult to add those new codes in my program.
Here is my Javascript Code: function validate(){ if(document.Enquiry.FirstName.value==""){ alert("Please enter Name"); document.Enquiry.FirstName.focus(); return false; }if(document.Enquiry.Address.value==""){ alert("Please enter Your Postal Address"); document.Enquiry.Address.focus(); return false; .....
I've been messing around and searching about trying to find something which will only allow one of the hidden div's open at a time. When a new link is clicked, the last div open closes. Unfortuanatly I haven't found anything yet.
I am just wanting to use Java to change one value in my code for my project but after having gone through the basics on the web, i seem no closer to finding the solution.I am wanting one JavaScript effect of 'onmouseover' to change the autostart value to 'true' when the preceeding img element is hovered on and to go back to 'false' for onmouseout. I was hoping i'd be able to work out a simple application for an if statement but am now unsure if i'll be able to work it out.Does anyone know a simple javascript that will do the trick?
I have a DIV blocked from data entry in IE, Firefox, Safari and Opera. Functionally all is okay -- super plugin! The only problem left is that the cursor does not change to 'not-allowed' on the overlay when I use IE 6,7 or 8. All other browsers render the cursor okay?
Here's the code: $().ready(function() { Protect('#divData'); $('#cbProtected').bind('click', function(e, ui) { if ($(this).is(':checked')) Protect('#divData'); else Unprotect('#divData'); }); }); function Protect(el) { $(el).block({ message: null, overlayCSS: { backgroundColor: null, opacity: 1.0, cursor: 'not-allowed' }});}; function Unprotect(el) { $(el).unblock(); };
The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).
One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).
how do I pass a var (in my case ssID, since have two slideshows) to onAfter? (I know there are three params passed to this fn already... how do I pass a fourth one??)
using js to force a specific anchor call to jump after the page completely loads. The reason I am doing this is because the page I am linking to with anchors takes a long time to load and a standard browser anchor link sometimes does not work 100%. With that said, I would now like to make the script I wrote universal to get ANY anchor param in the url and jump to that spot on the page. Right now it's coded to just look for "#anchor". I want to re-code it so it will look for "#" + "anyAnchorName".
There are 3 tables in DB group-set,group,users. Two different type of folders 1 is group-set which contains groups and another is groups which contains the users in group.group-setcan have multiplegroup-setorgroupas a child elements.groupwill have only users as child elements.useris a leaf node.how to load it with ajax. because ajax GET request passes "id" to load childs.. but in this case we need extra parameter in GET request i.e.typeto find out whose child it needs (group-set's or group's).type will determine what needs to be loaded. users or groupshow to modify get request generated on node expand with appending type parameter in treeview ??
