Hey guys,
I just got a problem which is I can't get the height property of a <p>.(use javascript document.getElementById(id).offsetHeight)
It works fine both in FF or chrome.
I have tried to set the style of the <p> to height:100%;/height:auto;
but both not work.
Please help me, thanks :D
I have a asp.net textbox(textarea which is in a repeater have single texarea for each record which are read only) I have button (open in new window) when i click on it the content of the text area needs to be rendered in a new window using javascript .
How do I test to see if links are external or internal? Please note:
I cannot hard code the local domain.
I cannot test for "http". I could just as easily be linking to my own site with an http absolute link.
I want to use jQuery / javascript, not css.
I suspect the answer lies somewhere in location.href, but the solution evades me.
Thanks!
What is the difference (if any) between the javascript strings defined below?
var str1 = "Somestring";
var str2 = 'Somestring';
"" and '' mean two very different things to me predominantly writing code in C++ :-)
EDIT: If there is no difference why are there two ways of achieving the same thing and which is considered better practice to use and why. Thanks!
I need some help finding the error in my javascript calculation.
I need to calculate the sum of my input boxes automatically and have my user be able to edit the calculation using + or - buttons.
The code I have already does the calculation automatically if you manually enter the numbers, but pressing the + or - does not change the calculation.
Here is the code:
<html>
<head>
<script language="javascript">
function Calc(className){
var elements = document.getElementsByClassName(className);
var total = 0;
for(var i = 0; i < elements.length; ++i){
total += parseInt(elements[i].value);
}
document.form0.total.value = total;
}
function addone(field) {
field.value = Number(field.value) + 1;
}
function subtractone(field) {
field.value = Number(field.value) - 1;
}
</script>
</head>
<body>
<form name="form0" id="form0">
1: <input type="text" name="box1" id="box1" class="add" value="0" onKeyUp="Calc('add')" onChange="updatesum()" onClick="this.focus();this.select();" />
<input type="button" value=" + " onclick="addone(box1);">
<input type="button" value=" - " onclick="subtractone(box1);">
<br />
2: <input type="text" name="box2" id="box2" class="add" value="0" onKeyUp="Calc('add')" onClick="this.focus();this.select();" />
<input type="button" value=" + " onclick="addone(box2);">
<input type="button" value=" - " onclick="subtractone(box2);">
<br />
3: <input type="text" name="box3" id="box3" class="add" value="0" onKeyUp="Calc('add')" onClick="this.focus();this.select();" />
<input type="button" value=" + " onclick="addone(box3);">
<input type="button" value=" - " onclick="subtractone(box3);">
<br />
<br />
Total: <input readonly style="border:0px; font-size:14; color:red;" id="total" name="total">
</form>
</body></html>
