how to get a js variable later in the html......My page is here: [URL]I want to access the 'selected' variable from the function in <head> later in the page, to complete a form:
<script language="JavaScript">
document.write('<INPUT TYPE="hidden" name="selected" value="'+selected+'">');
</script>
I'm looking for a way to define a function that's only effective inside
specified function.
Featurewise, here's what I want to do:
bar_plugin_func = function() { ...; setTimeout(...); ... };
wrap_func(bar_plugin_func);
bar_plugin_func(); // calls custom "setTimeout"
So while plugin developer thinks s/he's calling top-level function,
I want to hook it by somehow injecting local variable with the same
name.
Simply doing something like
;(function() { setTimeout = function() { ...my custom implementation
})();
is not ideal, as that'll taint global scope. Actually, I can live with
that for now,
but it's my technical interest to find a way to define it locally.
function test() {
var DIV = document.createElement('DIV');
}
If I never insert DIV to any node its parentNode is null and being a local variuable it's reference is lost.Is it destroyed?or do I have to add it to a node then use removeChild?

I was wondering if it is true that the Date object gets its date from the user's local time, if so, could the user "hack" the time by adjusting his local time?
View 6 Replies View RelatedI want to modify a local variable of the ready function set like so:
$(function () {
var modifyme = 0;
...
});
I cant change the code setting the ready function, as I am writing only a greasemonkey userscript. I already tried using the .data("events") method, but it never listed the "ready" event. Any function so I can modify the variable!
How to: pass local variable from <head> JS function to <body> textarea
I have a JS function in the head that calculates a variable. the function is triggered by the vevent of a button click. when calculation is done, how is it sent back to the page and placed in a textarea or textbox?
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?
Is there any way to get the variable name of an object from inside the object?

what I have is this function which reads the JSON attributes of crab_house, a JSON object:
But what I would like to do is something like:
I have a function that takes parameters of what the form name and the form object name is and then modifies the form accordingly. Now I can make it work fine if i make a separate function for each form object, but that seems very cumbersome. This is what I have
document.formName.formCat.selectedIndex;
i want formName and formCat to be variables so I can specify in the parameters which part of the form to deal with, but i get an erorr. Is this possible?
How can you use an integer as an object? The idea is to create dynamic object according to a particular id which is an integer
var newObject = function(integer) {
window.integer = {};
}
I cannot console.log(window.123), only console.log(window.integer) ...
how I create the object window.123 or perhaps, window.id_123 ?
How is it possible to take the value of a variable (in this case,
MODE_CREATE, MODE_UPDATE, etc) and use that as an object property name?
In the following example I want 'oIcon' object to have the properties:
mode1, mode2, and mode3.
This seems simple but I can't quite figure it out...
Any ideas anyone?
var MODE_CREATE = "mode1";
var MODE_UPDATE = "mode2";
var MODE_DELETE = "mode3";
var oIcon = {
MODE_CREATE: "create.gif"
, MODE_UPDATE: "update.gif"
, MODE_DELETE: "delete.gif"
};
var oTitle = {
MODE_CREATE: "Create a new item..."
, MODE_UPDATE: "Update this item..."
, MODE_DELETE: "Delete this item..."
};
I'm looking to do something like this:
function superDuperObject(range) {
this.startContainer = new superDuperObjectStartContainer(range);
}
function superDuperObjectStartContainer(range) {
this.calculatedContainerNumber = doSomethingAndGetSomethingBack(range);
return range.startContainer
}
function doSomethingAndGetSomethingBack(range) {
return
someCoolInformationThatICalculateInThisFunctionTha tNeedsTheRange;
}
var myObject = new
SuperDuperObject(DOMRangeObjectThatIDefindedEarlie rInCode);
// Show me the startContainer of
"DOMRangeObjectThatIDefindedEarlierInCode"
alert(myObject.startContainer);
// Show me the calculatedContainerNumber that I get from a function
that does stuff with the range passed to it
alert(myObject.startContainer.calculatedContainerN umber);
I have an error when I try to make:
CustomObj =
{
is_all : Compatible(),
Types :
{
PASS : CustomObj.as_all ? "ok" : "onok",
...
...
...
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 need to acsess an object property via variables, but don't get ahead.
Example:
var property = height;
"height" is a property of the object "flower". Now, I need a possibility to access "flower.height" with my variable property, means -->"flower.property" I tried everything like "flower.[property]" "flower.['property']" etc. but nothing did help.
I am fairly new to JavaScript, have been using VBscript before and JavaScript comes off a bit illogic...
Anyways, here's what I am trying to do:
function TestFileType(formname) {
fileName=document.[formname].img1.value;
apparently I can't reference a form object like this. What is the correct way of going about it?
I am trying to assign a variable to a jquery object that is found using the children() and eq() methods. This is a simplified version of the html structure.[code]Here is the jquery code. All I want to do is assign an object to the variable and be able to manipulate the object through the variable. [code]Again this is a simplified version of my code but the structure is similar.
View 2 Replies View RelatedI have an input form that accepts numbers. I am trying to compare the last field value to the current field value. My problem is that when I use the variable name of the last field in an object path, I get the error "null or not an object". The var 'L' is the problem in the statement below. If I manually type the field name in place of 'L', it works fine. How do I have to write this statement so 'L' works?
Problem statement:
c=window.document.save_info.L.value;

Below is the code that is using the name FFF in various places. The effect of all this is that the onclick function is not executed. I would expect a pop up alert when clicking the submit button. This only happens if I rename either the form id or the js variable. Can anyone explain what is going on here ?

How do I store an object reference inside a variable when I want the object reference to to reference the first "ul" html element nested inside the current object (as referenced by this keyword)?
var slideList = ???
I am trying to create a sliding menu.
I have an object whose name is mural. I have assigned the name mural to the title of an anchor element. When user clicks and element I want to store the title of the anchor in a variable called sprite. I then want to access that object whose name corresponds to the sprite variable string.
Here is my code:
HTML Code:
var mural= new Object();
mural.top='0px';
mural.left=-'510px';
var stamps= new Object();
stamps.top='0px';
stamps.left=-'1886px';
var sprite=$(this).attr('title');
$(".image-holder").css("background-position",'sprite.top, sprite.left');
It's not working because the the variable sprite is just a reference to $(this).attr('title'), how do I make it reference the object? Oh and I know that .cc jquery statement probably wont work, I'm not sure yet of the correct way to have two values that don't need quotations in as the second argument.
How can I avoid type-conversion (object variable --> string) when
passing an object variable to a function?
Example:
-->
catch(myerrorobject)
alert(myerrorobject.filename);
{
my_function('bla: ',myerrorobject);
}
<---
I get the "myerrorobject.filename" in the alert-Box, but I get an
"undefined"-error, if I try to access myerrorobject.filename (or other
properties) in the function "my_function". Why?
I was wondering if the following would be a valid JavaScript
assignment vor a variable and if anybody knows this to work in IE6 or
lower?
var someVar = (typeof(someVar) === Object) ? this : getVar();
function getVar(){
alert('getVar() called');
return(true);
}
alert(someVar);
alert(someVar);
It seems to be working in FF 2 an Safari 3.
Hey all, I'm using a fairly simple accordion script. When I went to take a gander at the page in IE I found that the onclick function of the script doesn't respond. It works in FF, Safari, Chrome and Compatibility Mode in IE 8
the error message IE gives me is
Message: 'h' is null or not an object
Line: 13
Char: 77
Code: 0
URI: http://proposalfor.us/js/script.js
The problem line (as far as I can tell) is:
this.a[s]={}; this.a[s].h=h=T$$(e,v)[0]; this.a[s].c=c=T$$('div',v)[0]; h.onclick=new Function(this.n+'.pr(0,'+s+')');
Well, it turns out IE8 has yet another problem. My code has a global variable (to the object) inside an object declaration that cannot be accessed by a function (that is also global).
The code is like so:
Code:
function myobject(params){
//public
this.initialize = function(){...}
//private
some variables...
//problem variable
var mouse = new Object()
mouse.x = 0;
mouse.y = 0;
//code...
slidecontainer = document.createElement("div");
slidecontainer.onmousemove = function(event) {
if(boo.isIE) {
e = window.event;
mouse.x = e.x + document.body.scrollLeft;
mouse.y = e.y + document.body.scrollTop;
} else {
e = event;
mouse.x = e.clientX + document.body.scrollLeft;
mouse.y = e.clientY + document.body.scrollTop;}}
//this function is in an interval
function moveslides() {
/* this is where I have the problem
It seems that the function doesn't recognize that mouse.x, or mouse for that matter, exists. Mouse is global to the object, so why can't this function access it?
*/if(mouse.x) {
code...
