JQuery :: Creating Function Based On Text Argument
Oct 21, 2009
All the function extending I see extends on an _object_. I want to extend on a string.
/**
* Returns a slug version of a string
*/
jQuery.extend ({
slug: function( text ) {
return text.trim().toLowerCase().replace( /[^-a-zA-Z0-9s]/g,'' ).replace( /[s]/g, '-' );
}});
I want to be able to do something like:
$('#form_element').val().slug();
The above does not work. I even tried modifying the 'trim' function in jQuery core to include the rest of the enhancements, but it didn't work.

how to you use the result of a function as the argument for another function instead of passing the actual function to it. i.e.
function foo2(){}
function foo(func){}
foo(foo2);
This passes foo2 to foo, can I do foo(foo2()) ? i.e. is the difference between whether a function is passed or evaluated dependent on whether you use "()" after the function name?

I have used an object in the past as a function argument, but this was for a plugin that I wrote. Using it in the architecture of a plugin it worked. BUT, this time, I just want to write a normal function, but still use an object to set defaults and pass in changes to those defaults through as a param. Is this possible, or do I have to make this a jQuery function like $.myfunction() ?

I have written the following code (quite meaningless. Just to check why setTimeout is not working in a similar real-life code) to enable the user to input a given time interval (hh:mm:ss) when a p is clicked, and then alerting the user with the time entered in the seconds portion one second after the div is clicked. But it is not working. I think the setTimeout is the culprit, the way I am passing parameters to the function inside it, but don't know where exactly am I erring.

How do you pass an argument to a function.
for example if you have a <span id = "test" onMouseOver ="myfunc(x)>
eg you have lots of differant span id's but you want then all to have a certain background-color with each individual on mouseover event without having to write separate code for each span id
eg <span id=" test2"onmouseover ="this.style.background ='red'>....

How can I modify any one of these global variable identified via a function
argument?
var x1 = "bla";
var x2 = "bla";
var x3 = "bla";
function modify(variable) {
???? [variable]???? = "blabla":
}
The following onclick should change the string value of variable 'x1' from
"bla" to "blabla", via the above modify() function.
<a ... onclick="modify('x1')">

How can I create argument defaults for a function? I have this function (the purpose of the lines I included were to set defaults if the user forget to input something simply to prevent an error.
Code:
addHSLink = function (hsElem, hsUrl, hsType, hsTitle, hsWidth, hsHeight) { //hsElem[string], hsUrl[string], hsType[string], hsTitle[string], hsWidth[string/number], hsHeight[string/number]
var jQElem = $(hsElem);
if (typeof hsUrl !== 'string') {
hsUrl = '[URL]';
} if (typeof hsTitle !== 'string') {
hsTitle = '';
} if ((typeof hsWidth !== 'string' && isNaN(parseFloat(hsWidth))) || hsWidth !== 'number') {
hsWidth = 800;
} if ((typeof hsHeight !== 'string' && isNaN(parseFloat(hsHeight))) || hsHeight !== 'number') {
hsHeight = 600;
}
//Some other code
}
I would like to save some programming space and time by finding another way to set defaults. I saw somewhere that you could set a default in the arguments list
Code:
function someFunction(aVariable = false) {
//some code
}
But when I try to do this with all my arguments, I get the error:
"Missing ) after formal parameters".

New to JS. Have ordered some new books, but need to get somethings going in the mean time. What I wanted to do is to link to a new page having a date range input in the form of 6 text boxes, 2 sets of mm-dd-yy, from and to, where the upon loading the page box 1 of the from would auto focus and then auto tab and then post where php could take over on the server side. Setting up the form and the lay out, no problem. Auto focusing went just like expected using the following code, included because on the next step everything fell apart.
Code:
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
So then the wheels came off and in response, began to simplify what was trying to be done to find where the issues were. As far as I can get working is:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html>
<head>
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
<script type="text/javascript" >
function myFunc() {
alert("is this working");
}
</script>
</head>
<body>
<input id="input1" name="input1" type="text" onkeyup="myFunc()" maxlength="2" value="type a No." />
</body>
</html>
First issue with this: When I first get to the page everything is just as ordered. The focus is on the text box and the default value is "type a No." When I press a key onkeyup, I bring up the alert box with "is this working" in it. But when I refresh the page with the refresh button, after clicking the "ok" on the alert box, the character that was typed in is still displayed. If I use the link to the page, or the URL from the address bar, then the page reloads properly with the default value, "type a No".
How do you get the default textbox value using the refresh button as apposed to reloading the page using a link or from the address bar? Using Firefox 8.0 more important at the moment: If I change the script to pass an argument to the function the script crashes. It does not pull up an alert box and freezes. My guess is that I'm doing something wrong on a concept level. Changed the default value of the text box to " ". Looked like to me there was an issue with the size specification and the default string length as you could only enter in a key stroke by highlighting the text and replacing it.
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html>
<head>
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
<script type="text/javascript" >
function myFunc(awe) {
alert(awe);
}
</script>
</head>
<body>
<input id="input1" name="input1" type="text" onkeyup="myFunc("123")" maxlength="2" value="" />
</body>
</html>

I am trying to pass an argument to a function to process server responses. My original line of code looked like this: [url]
This works well enough as is, but I am trying to pass arguments to the function, and everything I am reading says to contruct the code like this: [url]
Every example I have come across uses this same approach, but I keep getting the error "Expected ';'" pointing to this line and then the code fails to execute. I just cannot see where there is anything missing, and it looks pretty much identical to my examples.
I have also tried replacing the call to the function with the actual code in long-form, and the result is the same.

I want my (IE) Intranet users to be able to create a new Word document
based on a specified template.
The following works, but I would like to be able to pass the filename
as a parameter, as there are often multiple documents on the same page:
---------------Script Code Starts-------------
<script lang="Javascript1.2">
function NewDoc()
{
var oShell
oShell = new ActiveXObject ("WScript.Shell");
oShell.Run('cmd /K "C:Test.dot"', 0, false);
window.event.cancelBubble = true;
return false;
}
</script>
---------------Script Code Ends-------------
---------------Link Code Starts-------------
<a href=":" onclick="return NewDoc()">Create a new document based on
C:Test.dot</a>
---------------Link Code Ends--------------
I know to specify the document template name as follows:
---------------Link Code Starts-------------
<a href=":" onclick="return NewDoc('C:Test.dot')">Create a new
document based on C:Test.dot</a>
---------------Link Code Ends--------------
And change the "Function NewDoc()" in the script code to line to
"Function NewDoc(TemplateName)". The problem is that I don't know what
syntax to use to parametise the
"oShell.Run('cmd /K "C:Test.dot"', 0, false);"
line.

I have a form that collects information about up to 5 items. I would
like the user to be able to select from a drop down menu how many items
for which they want to compare information, and then have the form
change the number of input fields accordingly.
In other words, if the user selects enter info for 3 items, then input
fields for only 3 items are shown, if they change it to 4 items, then a
fourth column shows up in the table with the appropriate input fields.
