i have an html text box (which is part of a from) to which a value will
be entered by a user. i need to assign this value that has been entered
to a JS variable.
would the sxcripting be as simple as:
var nameOfVar;
nameOfVar = textBoxName;
So I am working on an excercise that the User puts in a Lastname, Firstname, and a score via textboxes. When the user pushes the add student score it should show up in the text area with this format " Brown, John: 92". When looking at the logic, I understand that each text box will need to be different arrays if im right, and then I will have to concat all three arrays into the format and assign it to a variable. Then assign the variable to the value of the text area. I just cannot seem to put the function together or how you would go about it. how to go about putting it together. The first code is my body of HTML I'm working with.
<body>
<div id="content">
<h1>Student Scores</h1>
<div id="buddy">

I currently have a table where the current cell (cursor hover) is highlighted along with the top cell in that column and first cell in row.I want to assign the values in these cells to input text fields. The first column cell is identified by Col1Cell[0] where Cell is the top table data cell of the current column.I can access the value of the cell by Col1Cell[0].innerHTML But when I try to assign this value to a text field nothing happens.I have document.getElementById("tableID").fieldID.value = Col1Cell[0].innerHTML

Is there a way to remove text portion from the HTML keeping the HTML
Tags using the browser, say javascript RegEx or something ?
I have seen lot of examples removing HTML tags to get the text but how
the reverse of it?
Via ajax, data equals <h1>Special</h1>
Code JavaScript:
function searchReplaceAndDisplay(data) {
data.replace('<','<');
data.replace('>','>');
$('#modal').append(data);
}
$.get('getSpecialsHtml.aspx', searchReplaceAndDisplay);
Right now #modal displays <h1>Special</h1>, as plain text.
How can I get #modal to display 'Special' marked up as an h1 element instead of text?
<h1>November<span>2009</span></h1>
making a variable equal the h1 html() without the span text.
// equals 'November2009'
var monthDelete = $('h1').html();
// I need just 'November'
I am creating a small CMS module for a client. I created a little form and when they click Submit, it goes straight out into an include (.inc) file, which is connected to the web page to be displayed.
The trouble I am having is that I'd like to create an additional button that will insert some text (certain html tags to make their life easier, etc) - I got it to work, actually. The script executes and the text is inserted - but once the script runs and the page refreshes (or whatever it does), the text then disappears. The only way I can seem to get it to stay put is when I use "onmouseup" instead of "onclick" - which means that every time the user accidentally mouses over the thing, it inserts the text.
I need to have a simple text input field on a html page. It needs the users to type in either:
And depending on whats entered this will then take them to the corresponding:
Is this possible with javascript?
var gE = function(s){return document.getElementById(s);};
var foo = gE("foo");
work, while
var gE = document.getElementById;
var foo = gE("foo");
does not?
When i assign some css properties should i allways use the postfix like

Any neat way to copy a snapshot of one array to another?
A normal assignment results in the second array pointing to the first,
with changes to either array affecting both.
As a trivial example:
var a=new Array();
a[0]="zero";
var b=a;
b[1]="one";
alert("a="+a.join("*")+String.fromCharCode(10)+"b="+b.join("*"));
.... this results in a and b being identical two-element arrays.
Is there any easy way to set array (b) to be a copy of (a) BY VALUE -
ie using the contents of (a) as they were at the moment of assignment,
but leaving the two arrays separate so that subsequent changes to one
array does not affect the other?
I have an index.htm page ready. I want to be able to put in javascript code into the HTML coding that will write the ip address of the actual server that is hosting the website into a hidden text box. Then I want to insert this ip address into a hyperlink in the original index.htm to link to another html page (this will be a SSL secure page instead i.e. [URL].Also vice versa. (With SSL index.htm page have code that writes ip into hidden text box then hyperlink to the original http index page)
View 7 Replies View RelatedI have the html contents from an iframe stored in a mysql data record. I now want to load that back into the iframe. I can assign the php var to a js var using PHP Code:
var scontent='<? echo ($html) ?>'
but the string has been saved to the db with newline chars in it and is causing a js error because it is being interpreted as an un-terminated string:
var scontent='<P>This is a test</P>

I am creating a tool to merge xml files using xslt usin
Javascript/HTML.
Basically the user browses (browse button) to where there xml file
are, then browses to where their xslt file (to perform an operation
is. Then they click an "apply" button and the result is output in
frame below.
My problem:
I have the tool working fine when I only have one input xml file (whic
is no good in a merge tool!!) but when I modify the code and ad
another xml field, the apply button will not work for two fields!
I think I haven't assigned the functions correctly to the xm
fields/apply button. Heres some of the code I suspect is wrong, but i
not sure where?? Code:
I'm trying to create a function that will return the value of responseXML so I can assign a variable to it.
Code:
ajax.downloadXml = function (url)

Stepping through the function, the onreadystatechange seems to never be executed, so nothing is returned. There's probably just a fundamental I'm messing up on.
3-level dropdown box: [URL]. Now in this dropdown menu if you select:
Category > Cars
Sub category Cars for Sale
Sub Sub Category Ibiza
What I want to do is two things:
1)Place a value on all the Sub Sub Category(ies) so for example the value of Ibiza I want to = 55
2)Then Grab that value? How would I get that value and grab it from POST?
I am barely familiar with javascript. I have this html code with an embedded iframe. The html file in the iframe refreshes every once in a while. That is fine. However, in IE, there is this annoying click with every refresh. I googled a bit and saw a few solutions. Seem to me that if I fetched the contents of the HTML file (AJAX call) and assigned it to existing document.
1. How do I assign an entire document in JS?
2. If I did this would this prevent the clicks?
I have a situation where I'm trying to assign a value to an elements innerHTML. When I do this, the value is assigned, but it causes havoc on subsequent javascript calls.I realize this is kind of vague but I'm at my wits end on what to do. I've tried assigning the innerHTML value "NA", just plain text, and it has the same effect.Without being too confusing, I have a table of data inside a <div> where the user can navigate up/down by pressing the <enter> key, pg up/pg dn and arrow up/arrow down. When they move from record to record, I'm highlighting the new row and "de-highlighting" the old row. The row has many fields but only one fill in field which is where the user enters the quantity of the item to be ordered. This is on a local network using the Firefox browser.
Without the above line, all is well. When I use the above line, it messes up the highlighting of the row but also makes the fill-in field "appear" disabled. What I mean by that is when you type a number, you don't see the value change (even though the field has focus and the value is selected) but once you leave that line, the value you typed then appears in the fill in. Normally the value will change as you type a new value.
I'm running a PHP script to check whether the user is logged in or not. If the user is not logged in they are redirected to the login.php page.What I would like to do is redirect them to the PHP page but also grab the URL they were previously on and assign it to a hidden field in the login.php so that I can redirect them back to the page they were on while keeping the URL bar clean.Problem, I know that PHP cannot recognize a hash [URL] so I would need to grab the url through javascript instead of PHP.

IE has no problem with this, but Firefox throws an exception - "Illegal operation on WrappedNative prototype object". Is it within its rights to do so?
I have a function whose parameter is a reference the element that called it:
function someFunction(el)
{
...
}
The function is assigned to the onclick event of some elements in the
HTML source:
<input ... onclick="someFunction(this);" ...>
and dynamically to others:
elRef.onclick = someFunction;
When someFunction() is called from the statically-assigned onclick, el
is a reference to the element. But when it has been added dynamically,
el will be either undefined (IE) or 'event' (Mozilla et al).
To assign the right value to el, I can test if el exists and if it does,
whether its constructor is some type of HTML element or 'Event'. But IE
doesn't support the constructor property for elements (or have I just
not found it yet?) nor does it understand 'Event' the way Mozilla does. Code:
Basically we are trying to simulate the tab key when the
down arrow key is pressed. (we know there are other way
to control focus flow but we use a lot of dynamic jsp fields,
that will make the flow control a nightmare, we just want
basic tabbing from the arrow key)
1)We are able to capture a onkeydown event and reasign it with another
key value with no problem within an html document without a form.
example:
var ieKey = event.keyCode;
if (ieKey == 40) {
event.keyCode = 9;
}
however as soon as we insert a form tag in the document, this stops
functioning. The asignment seems to be fine as an alert clearly shows, but the
instruction seems to be ignored. Code:
