未在JavaScript中设置Div高度和宽度

Question

I am trying to set the width and height of a div in javascript but it is not being set. I have tried a lot but nothing is working. Here is what i have tried,

<div id="d1">asdasd</div>

<script>
    var d = document.getElementById("d1");
    d.style.width = "100px";
    d.style.height = "100px";
    d.style.cssText = 'border:1px solid black;'
</script>

Please check what is the problem!

Answer 1

I think d.style.cssText overwrites width and height properties

Try this:

var d = document.getElementById("d1");
d.style.width = "100px";
d.style.height = "100px";
d.style.cssText += 'border:1px solid black;'

Answer 2

As karaxuna mentioned, your d.style.cssText is overwriting the width and height settings. Simply changing your code to either this:

var d = document.getElementById("d1");
d.style.width = "100px";
d.style.height = "100px";
d.style.border = '1px solid black';

or this:

var d = document.getElementById("d1");
d.style.cssText = 'border:1px solid black;'
d.style.width = "100px";
d.style.height = "100px";

works perfectly.

Answer 3

This works:

<div id="d1" style="border:1px solid black;">asdasd</div>​
<script>
var d = document.getElementById("d1");
d.style.height = "200px";
</script>

Answer 4

An alternate would be to define a new style element in CSS and simply set d.className to that css element.

I guess d.style.cssText is problem

Answer 5

Your problem is with d.style.cssText = 'border:1px solid black;' . it is overriding the width and height set by JS .

Answer 6

Change sequence of your JS statements it will work ie

<script>
    var d = document.getElementById("d1");
    d.style.cssText = 'border:1px solid black;'
    d.style.width = "100px";
    d.style.height = "100px";
</script>

Better put width, height properties in style attribute only. ie

d.style.cssText = 'border:1px solid black; width:100px; height:100px'

or in CSS class

Answer 7

d.style.cssText = 'border:1px solid black;'
d.style.float="left";
d.style.width = "100px";
d.style.height = "100px";​

You neeed to use float:left attribute.

Answer 8

I don't know what your problem is but I've used this and this worked

    function fnc1()
{
    document.getElementById("d1").style.width="100px";
    document.getElementById("d1").style.height="100px";
    document.getElementById("d1").style.backgroundColor="red";
}

HTML:

<div id="d1">asdasd</div>​

Javascript

document.getElementById('d1').style.height = 90+'px';​

working demo here ( works fine with chrome, din't check with other browsers )
