I am trying to create a custom method for all Strings.
Code:
var chkStr = {
isBlank: function() {
if (this.length < 1) return false;

I am getting a Quote: form.formName.field.value.isBlank is not a function error.
in PHP I can create a multi-dimensional array with strings for keys,eg
$arr['key'] = array("item 1","item 2");
This works if the string is a variable as well, like
$key = "MyKey";
$arr[$key] = array("item 1","item 2");
I'm trying to something similar in javascript, but with no luck

I have used `jQuery.validator.addMethod` to create a custom validate method that will make sure there is at least one row in my data-entry table. Using Firebug, my breakpoint in the method isn't being hit at all. Am I missing something? Note: I am sure there are problems with the validation method itself, but that is because I can't debug it yet. I am still very much a novice with JavaScript.

I have added a method on jQuery validator like this
$.validator.addMethod('myEqual', function (value, element) {
return value == element.value; // this one here didn't work :(
}, 'Please enter a greater year!');
$.metadata.setType("attr", "validate");
[Code].....
In the new version of jquery.validate (1.5.3) there is an option to get a remote error message from the server for invalid elements. I did not find what should be the exact response from the server for producing such an error message. From the documentation: "The response is evaluated as JSON and must be true for valid elements, and can be any false, undefined or null for invalid elements, using the default message; or a string, eg. "That name is already taken, try peter123 instead" to display as the error message." But if i return a string, isn't it evaluated as true ?

As far as I know, there's no event for which a text in a textarea is highlighted. For instance, I want an event to fire when the word "your" in the textarea below is either clicked, highlighted, or brought into focus. HTML Code: <textarea> This is a text area... your text here
View 1 Replies View RelatedIm trying to create a custom selectbox and Im having some problems, with it. What Im trying to do is have a function that loops through all <select> tags and find ones that only have the class name of "select" and then from there they get a custom select box. From there I have a variable passed in order to get the option. I created a few elements and etc... So at this stage Im just trying to get the text from the <option> tag within each individual <li> element and I can't get it working.
View 9 Replies View RelatedHow do you create custom jQuery functions? I've tried numerous tutorials on the net and everyone results in firebug saying my function doesn't exist.
Is this the correct way to define a custom jQuery function:
Code:
I want to create a custom radio button. Basically I would like an image to act like a radio button. When selected the image border changes to highlight it. When a different image is selected it's border becomes highlighted and the previous selected image's border returns to normal. Only one image may be selected at a time. A value would then be passed in the form when submitted. I am wanting it to act like the way in print preview you can select the page orientation (portrait or landscape) by selecting the appropriate icon.
This is the code I came up with. It seems to work well but I thought someone here might know a better way to do this. To test subsitute your own images with file paths.

I'm trying to create a function to show a custom message as a tooltip when a user hovers over a table row.
My tr tag looks like this
The javascript function looks like this:
jQuery seems to be loaded correctly, as I get the alert. I don't get the tooltip, however.
What I'm trying to do, in case this is totally retarded and impossible to see, is to hover a tooltip over the clicked row instead of passing it in as a variable.
I know CSS3 is at the stage now where we can use this feature comfortably across all modern browsers, but what else can be done via Javascript/Jquery to create our ever-so beautiful rounded corners ? Im trying to achieve a fairly consistent look "cosmetically" in all my sites going back as far as IE 7...For example my second site Ive built PAT Tester providing PAT Testing in Birmingham Worcester Bromsgrove Redditch Dudley Worcestershire West Midlands utilises CSS3 and looks ok in the modern browsers, but go back to IE8 and "yuck" its all squared out maaaan....!

I'm using jquery/ajax to create some links with window.open method. Here's the relevant code:
$("#content").empty();
$.ajax({
type: "GET",[code]..........
Basically, when you click a link a function is called with a parameter based on the particular link you run. Then the code runs through an xml file, and if the parent of the nodes I've cyling through has a value equal to the parameter past to the function, that node is used to create a new link with window.open function attached to it.It all works, or seems to, and when I alert what is being built, it looks right to me, yet the links don't work.I've attached a copy of one of the alerts of one of the links as it's built.
I'm trying to do something, but I don't know if it's possible.
Basically, I want to have a public static class method that could
access a private object's method. I would like to be able to do :
Class.method(InstanceOfClass);
The method would then access a private function from Class by doing
something like
function method(param) {
param.privateMethodOfClass();
}
I've done a lot research and experimentations but just can't come up
with a solution... I don't even know if what I'm trying to do is
possible.
Why is the callwhy is the slice method only a method of an Array instance? The reason why I ask is because if you want to use it for the arguments property of function object, or a string, or an object, or a number instance, you are forced to use Array .prototype slice.call(). And by doing that, you can pass in any type of object instance (Array, Number, String, Object) into it. So why not just default it as a method of all object instances built into the language?In other words, instead of doing this:
function Core(){
var obj = {a : 'a', b : 'b'};
var num = 1;[code]....
//right now none of the above would work but it's more convenient than using the call alternative.
}
Core('dom','event','ajax');
Why did the designers of the javascript scripting language make this decision?
I have two methods and I would like to call somename1 method from within somename2 method. I have tried several ways to do so however I keep getting "TypeError" or "RefernceError" I have tried several ways to reference but I am still unable. What am I doing wrong. I would think this would be easy to do.
View 1 Replies View RelatedI'm having difficulties arithmetically manipulating form element values.
I've entered data into the form, and I fetch them using a js, as:
p7Left = Number(document.form1.elements["p7_left"].value);
p7Right = Number(document.form1.elements["p7_right"].value);
...
...
scoreLeft = Number(document.form1.elements["left_score"].value);
scoreRight = Number(document.form1.elements["right_score"].value);
Then I add these as follows:
scoreLeft = Number(scoreLeft + p&Left + ...... +);
This does what I want; without the operator 'Number' I get a concatination
of the various variables (as expected). Is there some way of globally
defining all variables as numbers instead of strings?
Safari and FF seem to allow this:
var wiggy = "ABCD";
ch = wiggy[2]; // ch will contain the character 'C'
however my JS book seems to insist that I do this:
ch = wiggy.charAt(2);
and indeed doesn't appear to mention the first method at all.
Since for my particular purpose I want to treat the string as an array
of single characters, I prefer the first method rather than the second.
Is there any reason not to pursue this approach?
I have two strings that I need to compare and modify when there is a
matching value in the two. If strA = ??,' then I need to remove
the value ??,' from strB and the new value would be strB =
??,12935'
strA = ??,'
strB = ??,12937,12935' (these could be any values in any order)
I'm not sure where to begin on this.
