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')">
Given the following code:
var xf2;
function f1()
{
if (document.createElement && document.body && document.body.appendChild) {
xf2 = new f2(arguments[]);
}
}
I am getting a syntax error in the "new" statement following the [].
How do I pass the variable-length arguments list received by f1 on to f2?
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 a class and function within it, like so

That code shows an alert box with 'mb_c is 1' and next alert box as 'other mb_c is undefined'. How do i access the mb_c which is member of Order class within the setup function which has an argument mb_c ?
I am trying to pick the larger of 5 numbers and sometimes there is a tie. I would like to prioritize variable c1 if there is a tie.

confirm("Form is INVALID");

exit;i have 4 different messages that i want to choose from to be displayed in the js script, and I want to store the message that i want to use in a PHP variable along the way. the variable is: $Alert_Message . i am trying to do this with my confirm() function in js:confirm($Alert_Message);the code is not registering, so something is obviously wrong. can i reference PHP this way in a js script? if not, how would i go about doing this another way? can i change a js variable along the way in my PHP code instead, and then reference THAT variable when i get to my js script?

I declare multiple variables halfway down the page. The number between "mech" and "Num" is generated dynamically in the XSL. Later on I need to reference that variable in a function, but I need to build the variable name in script. How do I convert it from a string reference to a ref to the global variable?
function changePreference(pos,mt){
//mt does not reference mech2Num, I need it to.
}
changePreference(2,'my' + pos + 'Num');
var mech1Num=1|2|3|4|5|6;
var mech2Num=1|2|3|4|5|6;
var mech3Num=1|2|3|4|5|6;
I have an error when I try to make:
CustomObj =

but in an object literal notation I cannot use a parent object
variable? or
can I do to create a global variable inside my parent class
(CustomObj) and
than to use in my children objects like Types?
I am wondering what the normal practice of creating an index variable is in javascript. I am wondering because I have just entered learning javascript through jquery. There is some pre-written code I am using to learn by and I am unsure of how their index variable is working in the code.
Here is the code:
Code:
jQuery(this).find("li").each(function(n) { // <-- I see that 'n' is the index

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'>....
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() ?

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".

View 1 Replies View RelatedNew 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 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.

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.
I am new to Jquery and would like to know, when we write a Jquery function and pass 'e' or any other word or letter as first argument, what does it represent? Also If I want to pass some parameter to my function along with 'e', how can I pass it?
