Concatenate Dynamic Variable Names
Jul 23, 2005I have a table that I populate with an array using ASP. As each row is created, the form object names are appended a numeric, such as:
i = 1
<select name="select<%=i%>">
...
...
...
i = i+1
next
I then pass "i" to a javascript function, so that I can access the values of each form object. I can't figure out how to properly concatenate the "i" and still allow access to the value in the form object. Currently I have:
var ps = 'platSymbol' + I;
alert(ps)
var sel = 'document.frmUpdPlatGrp.' + ps + '.value'
alert(sel)
I know I'm wrong, as this comes back as a complete string. Ultimately I want to have something like this:
var s = document.frmUpdPlatGrp.platSymbol2.value - so that I can actually get the value.
Ability To Refer To Function By Variable
Mar 26, 2010I have a function that sets a value of this.name. If I call a function of that function (is there a better term for that?), I can get the value of that name with this.name. However, if I save that function's function as a variable, and THEN call it, this.name is undefined.
I don't think my vocabulary is clear enough, so here's my example:
function Ninja(name){
this._name = name;
this.getName = function(){
return "ninja "+this._name
}}
sam = new Ninja("sam");
assert( sam.getName() == "ninja sam", "Ninja's name is ninja sam" );
sam2 = new Ninja("sam2");
sam2getName = sam2.getName;
assert( sam2getName() == "ninja sam2", "Ninja 2's name is ninja sam2" ); //fails
log("Ninja 2's name is actually "+sam2getName()) // actually "ninja undefined"
(Note: Use of "ninja" and assertions are because I was playing with the code in John Resig's java runner thingie: [URL]). The reason I want to be able to refer to a function by a variable is because I want to pass the function to something else that requires a function to be passed in, such as an ajax callback or something. Anyway... why is this.name undefined in the second example?
Refer To Text Of Url
Jul 20, 2005How can I access the text of an url via javascript, ie. get 'foo' (and
send it as parameter in goto(), in example:
<a href="javascript:goto([foo])">foo</a>
Or refer to it globally?
document.links.href.text.value ?
this.href.text ?
JQuery :: How To Concatenate Text
Nov 18, 2009I've tried various methods but haven't had any luck as of yet. I'm returning a series of 4 objects via AJAX calls. When each object loads, I'd like to iterate through it (no problem), and populate the "value" attribute of a hidden input field with each value from the object. I can't seem to find a way to intermingle jQuery and '+=', or find a jQuery substitute.

View 1 Replies View RelatedSubstring A Value For Display And Concatenate For Validation?
Feb 28, 2006I have a validation script for upc codes which is currently working for
values that are entered into one text box. I've been asked to break up
the text box into 3 separate fields to accept the 1st digit, middle 10
digits, then last check digit. What I'm doing is substringing the
initial values then concatenating them. What I'm not sure of is, how to
handle the validation. I was previously firing an onBlur after the text
box but now that I have three, and I need the values to concatenate
into one for the validation. Should I just fire a function after the
3rd field that concatenates the 3 values, then pass that value to the
validation function? Or is there a better way?
I was also wondering if there was something I could find like an input
mask, but something that could just "overlay" on top of a regular text
box with one value which could give the appearance of having
separations for certain digits, in this case the first and last.

How To Refer To The Original Parent Page
Nov 23, 2004I have a regular html page called a.html
this page opens a modal dialog window called modal1.html
modal1.html contains a 'Next' button.
when the button is pressed the modal1.html is replaced with modal2.html
modal2.html contains another button.
when its button is pressed, the modal dialog window should close and the location of the original page a.html should change.
I am trying to do something like:
//window.parent.location.href = 'anotherPage.html'
window.opener.location.href = 'anotherPage.html'
window.close();
I cannot use window.opener in modal2.html because its opener is actually modal1.html.
In fact anotherPage.html is opened in a whole new browser page
How can I refer to a.html in this chain?

JQuery :: Refer To Object's Property Inside $.each()
May 19, 2009function JGallery(){
this.name="defaultGallery";
this.images=[{//some JSON here}]
this.render=function(){
[Code].....
I've tried to debug it in firebug, but I guess there is a problem with the scope of the 'this'. The 'this' in
//i want append div with id of the name property of jgallery class
$("<div></div>").appendTo("#container").attr("id",this.name);
seems to refer to the iterator in the $.each().
I've tried to do this.this.name but it still doesn't work. Is there any way to allow me access the property of the Jgallery class?
Onclick Refer To Parent Object Method ?
May 12, 2010I am creating an application that uses as much Object Oriented code as I could (mostly to learn it).
I have an object called 'photo' that contains two Image() objects 'fullImage' and 'thumbnail'. All is fine and dandy, I can read the thumbnail and the full image, and their associated properties just fine.
But what I can't seem to do is make the thumbnail's onclick event refer to one of the object's methods.
Here is a greatly simplified version of the object's code.
Code:
So, the thumbnails div gets populated with the thumbnails fine. But for the life of me, I cannot figure out how to make the onclick call the photo object's "editPhoto" method.
Will the way that I am creating the objects using the same name for each one, result in only the last one created being accessible. If so, do I need to create an array of objects so I can uniquely identify each one?

JQuery :: How To Refer Nested Field In Multidimensional Array
Sep 8, 2011I'm using getJSON to retrieve information from a header record and the corresponding detail records and display the detail records in a table. The PHP script that is called returns a JSON string (via json_encode) that looks like this:
{
"srn":"1",
"invNo":"1",
"custNo":"39750",
"purchOrd":"PO12345",
"shipVia":"our truck",
"jobNo":"E001-11",
"invDate":"8/3/2011",
"taxCode":"1000000",
"shpName":"testName", .....
Here is the html table:
<table><thead><tr>
<th colspan="2" >Item Description</th>
<th>Quantity</th>
<th>U/M</th>
<th>Item Price</th>
<th>Item Amount</th>
</tr></thead><tbody>
<tr class="p_row_1"> .....
And here is the $.getJSON:
$.getJSON("GET_INV_INFO.php",{srn:'<?php echo $srn; ?>'},function(s){
// Get Header Info
$('#ip_invNo').html(s.jobNo);
$('#ip_invDate').html(s.invDate);
$('#ip_custNo').html(s.custNo);
$('#ip_purchOrd').html(s.purchOrd);
$('#ip_custName').html(s.custName); .....
My problem comes in the getJSON section where I'm trying to populate the table with a record. I don't know how to refer to the different fields in array 's'. I've tried the following and many variations, but to no avail:
$('.p_row_'+i+':nth-child(1)').html(s.row.i.itemNo);
$('.p_row_'+i+':nth-child(1)').html(s.row[i].itemNo);
How do I refer to a nested field in a multidimensional array like this?
