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?
Value entered in textarea is: "this "TEST" is not going well"
JS sends to server this value: "this "TEST" is not going well"
How to force JS not to convert the string ? I want JS to send exactly what
is typed in the form controls. Is there a function to call?
Let me preface this with the usual disclaimer: I am new to this and have only been programming with Javascript, PHP for about 2 weeks now and have been lucky enough to have resolved the issues I have encountered. This one however is puzzling to me.
I have a HTML form created that collects member information. It calls, on submit, a confirmation page that lists all the data fields entered. This all works great. However, when I then post the variables from the first html form page from my second confirmation html page to my PHP script, using document.write with input type=hidden and inserting the address variable into the value field, the Javascript only passes this variable up to the first space. It is the only variable I pass that has a space in it.
I have verified that the variable does indeed contain the whole address and I have also verified when I execute the following: document.write ('<input type="hidden" name="address1" value='+address_1+'>');
the address_1 parameter passed to the php script only passes the string up to the first space.
I even tried to put fixed text in there instead of a variable (e.g.)
document.write ('<input type="hidden" name="address1" value="555 Drury Lane" >');
and it still only passes the string up to the first space (555).
I show the variable address_1 on my confirmation page and it shows the entire string.
I checked what was being passed and it seems that the Javascript is the culprit (or more likely the Javascript creator - me)
All my other variables (which don't have spaces) pass to the php script with no problems.
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.
let me know how to convert a string to double in Jquery. String is an amount field like (3,154) which needs to be converted to Double.

I'm currently constructing a javascript "terminal" on a site I'm building so that I can test objects and functions outside of the web developer terminal in google chrome.
Given that I have active javascript defining an object called item, typing item in the chrome terminal returns Object and goes on to list the properties of item.
Moreover, I can define a function in the terminal like this: function(x) { return x }, and then function(item) will return Object and list the properties. However, if I use form data and user input in the place of the argument, the datatype becomes a string and not an object, so typing item in the form and clicking a button that performs function(document.form.text.value) returns the string item and not Object.
Is there any way to convert this primitive string to an object so that I can then iterate through properties, and so on?

I have a for loop: Code: for( var i = 0; i < aInput.length; i++ ) I want to use this i variable to concatonate it as a string to find an input box
Code:
var j = i;

qualname.toString();
if ( inputName == ( qualname ) )
{
Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc...
I wrote a .repeat(n) function for strings which seemed to work fine:
String.prototype.repeat = function(n) {
// repeats the string n times
if (n<1) return "";
if (n<2) return this;
for (var aStr = [this];--n>0;) aStr.push(aStr[0]);
return aStr.join("");
}
Only I was a little surprised to get "object" (instead of "string")
when I tried:
alert (typeof ("x".repeat(1)));
I fixed this by modifying ...
if (n<2) return this+"";

I have a image gallery that gives very nice popup windows when you click the thumbnail for the larger picture. The problem is that when you hover over the thumbnail(link) it doesn't change the cursor type to a hand which makes it hard to know that it's a link....
View 1 Replies View RelatedUsing Jquery, and I'm trying to make a element positioned either from the top or bottom based on where it is in a grid.
Code JavaScript:

So I've got a nested object that has this structure:
{"big_s":
{"s1":{"params":{"p1":"stuff","p2":stuff2"","p3":"stuff3"}},
"s2":{"params":{"p1":"stuff","p2":"stuff2","p3":"stuff3"}}
}
}
how would I go about removing one of the inner objects - s1 or s2? I've tried all sorts of ways but can't seem to get anything to remove an item from a jQuery object.
I have a variable that contains Form Elements. So these elements can be eitther a :text either a :check box See code below:
var currentValue = $(targetedInput).val() ? currentValue = $(targetedInput).val() : currentValue =$(targetedInput).is(':checked')
I was hopping that this line of code would assign a different value to currentValue depending on what kind of object i have. My idea was that If the current Object is a check bot it doesn t have a val attribute..
What type of variable is an empty array element? I thought it was undefined, but i noticed that they have different behavior than undefined does:
var r=Array(1);
var s=r.concat([0,"",null,undefined]);
alert (s.toSource()) //==="[, 0, "", null, (void 0)]"
typeof s[0] //==="undefined"
typeof s[4] //==="undefined"
As you can see, 0 and 4 both === undefined. Yet, they don't have the same toSource()...
Is this special type named anything specific? Or more importantly, can it be detected outside of an array as being distinct from undefined? I am thinking this would be the same type as ({}).nonProp ...
I guess the question is actually, "can you tell the difference between uninitialized and undefined"?

I'm apparently misunderstanding what I'm reading on prototyping. My main task is to squeeze some performance out of an app that's a bit slow on IE, and it looks like large Arrays and their overhead may be part of the problem. I'm trying to replace those with my own array type based on Object and extend it with helper functions like .length. Here's a munged sample of what I've tried:

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?

"typeof" doesn't work -- it returns "object" for all objects:
x = window.open('http://www.yahoo.com/');
alert(typeof x);
And I found this page:

which claims: "To get the type of an object x, use x.class".
However, that doesn't work in IE 6 so it must be Mozilla-only.
I'm writing a debugging script and I'm passing a function an object to iterate through:
myObject = {a:1,b:2}
debug(myObject);
I'm wondering if there is any way to get the variable's name as a string("myObject"), so something like a .name property:
function debug(obj) {
alert(obj.name); // would alert "myObject"
}
Is there any way to do this?
