Cannot Get Method Argument Passed As Function Parameter

Dec 1, 2011

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>

Passing A Function As An Argument And Using The Evaluated Functionas An Argument

Nov 30, 2006

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?

JQuery :: Object As Function Argument?

Jun 23, 2009

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() ?

JQuery :: Function That Is Being Passed An Array Of Nodes ?

Nov 20, 2010

This is the first question I couldn't find answered by Google! No doubt the answer is out there, but...

So I have a function that is being passed an array of nodes: some of them plain vanilla DOM nodes, (say, those created by document.createElement), others are jQuery nodes (say $("<div></div>").

What's the best way to determine if a node is of each type? I can obviously look at the node contents, but I wondered if there was a "best practices" here?

JQuery :: Get $(this) To Work In A Function That Has To Have Variables Passed To

Apr 28, 2011

I want to call a javascript function when a <span> is clicked, pass two variables to it, and then use jquery to hide that span.

A simple example is:

The variables (1,3) & (8,9) are loaded dynamically with a php script. Adding the two variables together isn't the intent of the script, but it seems the simplest way to explain what i'm after.

So how do you get $(this) to work in a function that has to have variables passed to it?

JQuery :: Function With Multiple Parameters As Argument In SetTimeout

Feb 22, 2011

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.

<html>
<head>
<script type="text/javascript" src="jquery.js"></script>

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.

Cant Use Passed Variables In Function

Oct 11, 2010

I'm trying to reuse a script I have but, I'm not able to due to the fact I can't use some variables in a function.

I would like to know why I am not able to use passed variables in javascript.

For example: I call a function submit_data( 'newDomainForm', 'add_domain', 'list_div' ), in the function itself I would like to use the form name (first variable passed) as document.form.domain_name.value.

Later on I would like to use the div id: list_div in document.getElementById( div_id ).innerHTML. This doesn't work.

I have to put the name of the actual div like this: document.getElementById( 'result' ).innerHTML

And to get the value of a form element I have to put the actual name like this:

How To Create Argument Defaults For Function

Mar 2, 2010

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".

Variable Not Being Passed When Calling Function?

Aug 13, 2009

The code below is the relevant part to an autosuggest feature. The variable that isn't being passed is "firstValidIndex". It is being set appropriately, but when it is used in "sortArray()", its value is 0.

// here we must check to see if where the string matched was at the beginning of a string inside this.aNames
// firstValidIndex is the first index where the char is at the beginning of a string
