Return An Object To A Div Area?
May 7, 2009
I have three buttons set up using onClick. These buttons are used to display the differing results from an object. They work except the results are displayed on a new page. Ive been trying to get them to display the results in the same page using a div. The problem is I cant get them to work properly i.e the result wont display at all in the div area.
Here is my code
Code:
<body>
<input type="button" value="emp1" onClick="document.write(ger.getFullName())">
<input type="submit" value="emp2" onClick="document.write(tom.getFullName())">
<input type="submit" value="emp3" onClick="document.write(mar.getFullName())">
[code]....
How do i get the results to display in the div?

reSplit is used to return an object from a string of name/value pairs.
pass reSplit()your own delimeters or use the defaults.
String.prototype.reSplit= function(d1,d2){
if(!d1) d1= /s*;s*/
if(!d2) d2= /s*=/;
var Obj= new Object, tem;
var A= this.split(d1);
var L= A.length;
for(var i= 0; i< L; i++){
if(!A[i]) continue;
tem= A[i].splat(d2);
Obj[tem[0]]=tem[1];
}
return Obj;
};
String.prototype.splat= function(delim){
var ax,L;
var d= this.match(delim);
if(!d) return this;
else{
ax= d.index;
L= d[0].length;
return [this.substring(0,ax), this.substring(ax+L), d[0]];
}
};

i've seen this code at work which i do not get.
var Key = {
'Number1': 49, 'Number2': 50, 'Number3': 51, 'Number4': 52, 'Number5': 53, 'Number6': 54, 'Number7': 55,
'Number8': 56, 'Number9': 57, 'Number0': 48,
};
I need to return a var element from Key based what a var containing a string contains e.g
var string = "1"; an example
return Key.Number1
How would I do this using a for loop and not having multiple if statements

I'm writing a function that substantially load a given image making a fadeout/faidin waiting 'till the complete load. The function is named "loadImage" and I would like use it in the following way:
$('#image img').fadeOut().loadImage(src).attr("src",src).fadeIn();
In order to make the image disappear, load... change the attribute "src" of the image and then re-appear. The code for the function is:
(function($) {
$.fn.loadImage = function(src) {
var img = new Image();
$(img).attr('src', src).load(function() {
return this;
});
}})(jQuery);
But when I run it I get the following error:
$("#image img").fadeOut().loadImage(src) is undefined
I think that the function don't return a "valid" object to make it chainable, isn't it?

I am confused about what the return keyword is actually returning when returning an object, a primitive, or a function. My confusion is compounded by the fact that I'm not sure if a function is an object or not. According to the book JavaScript Programmer Reference it is: "All functions in JavaScript are first class objects , meaning they can be passed around like any other object reference. In fact, regardless of how they are created, functions are instances of a global object named (aptly) Function."
However, someone else states that a function is not an object. An object is a set of primitives and references. A function is executable code. Functions become objects through the use of the new operator. Yet, in the book I mentioned, it says you don't need the new keyword to execute the function as an object, as it already inherits from the object Function when the function keyword is used:
function functionName([argname1 [, ...[, argnameN]]])
{
statements;
}
So there's one source of contradiction. Now the bigger issue is what is going on when the return keyword is used. Notice the Validation() function returns an object as its last expression. This technique is common, where you return an object which contains functions in form of object notation. I believe this is done so that we create a closure so that when the intepreter exits the Validation() method, since we created a closure by returning an object, which contains the inner functions addRule and getRule, the local variables of Validation() are not destroyed, given that we can reference them through the two inner functions that make use of the local variables of the outer function. So when we use the return keyword on an object literal, and then exit the function, when we call one of the inner functions as we do later:

I am looping through an array of objects and creating an <li> element for each one and appending to a <ul> in the DOM. Works fine.During the looping I am also attached a 'details' object as data for the list element:$(thisListItem).data('details',{<obj>});Later, I am using the selector:$('ul#images_list li')to attach an on click function for each <li> element.In the click handler I am reading the data 'details' object for the <li> element:dataDetails = $.data(lotImage,'details');and, using the jAlerts plugin, I am opening a jPrompt which asks for the user to enter a price.
The jPrompt call includes a callback which receives the entered value as a parameter. The callback uses the value to 'post' the updated value, via $.ajax, to a server side unction.After OK is clicked in the jPrompt popup, in Firebug, I get an error that the dataDetails is undefined and it lists the line number in the click handler where I originally read the data object from the <li> element.I don't really understand why it should care after the click event has fired and the jPrompt callback has been invoked

I have a page with links that use jQuery to load individual pages of content into a main content area. On one of these pages, I want to be able to link to a specific anchor. (ie, when you click the link named "exec" on the main page, it loads the "services" page and then scrolls to the "exec" div.

Everything works beautifully in FF and Opera but in IE, I get an error message saying "top is null or not an object". It's referencing the line where "target_offset.top" is called, but this is legitimate syntax, so I don't understand the problem.

1. When I have the "<textarea>" code lines in it put a text-area on the page, but it puts all of the code following that first text-area line into the text-area box and doesn't execute that segment of code.
2. When there is no "<textarea>" (for the sake of seeing if the rest of it worked) it doesn't check the survey.
I'm stumped and can't figure out what to do at this point Code and pictures follow:

I have come across an issue that only happens with IE.I have a custom save function that is designed to handle different ajax submits but I will simplify it for debugging. The issue is that once I make a submit everthing is fine at first. Then once I try to submit a second time it craps out. I am checking to see if there is an onsubmit function and then executing it like so before continuing. After the inital submit it is no longer found. When I alert the typeof document on the form it returns object but when I add the onsubmit it says object expected or object is null or undefined.
Code:
function secureBarSubmit(formId)
{
alert(typeof document.getElementById(formId)); // object always
alert(typeof document.getElementById(formId).onsubmit); // func first time then it is broken

Can assign a new function to a built-in object in Firefox:
But IE and Opera don't have a MouseEvent or HTMLElement that can be set up in the same way. Can you do this in IE or Opera, or just Firefox, and maybe Webkit?

every time I try and alert:
[ { number:0, secondnumber:0 }, { number:2, secondnumber:1 }, { number:1, secondnumber:2 } ]
it just shows [object object], [object object], [object object]. Why is this and what can I do to make the record be shown as it is above in an alert?

Is there any way at all to create a new template object that inherits from the built in Date object so as to be able to add new methods to that child object without adding them to the built in Date object? I've tried everything I can think of and as far as I can tell it keeps referencing the Date function instead of the Date object and so doesn't work.

I am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.
My code is as follows;
Code:
My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?

I created a method for displaying an object's properties:
As long as renderfunction = false, the object is fine coming out of this function.
However, if I change renderfunction to true, all my properties become undefined. Why isn't this working as I expect it to?
