javascript - javascript move using div width

Question

I have the following code and it seems like the .style does not recognize my variable wid! what is wrong with it?

var wid = document.getElementById("bd").offsetWidth/2;
obj = document.getElementById('div1'); 
obj.style.left = wid.toString();

'bd' is the id of my body and 'div1' the id of the div i want to move. If I just use the following, it works fine:

obj.style.left = '10px';

您不需要使用toString，只需附加px到数字：

var wid = document.getElementById("bd").offsetWidth/2;
obj = document.getElementById('div1'); 
obj.style.left = wid + 'px';

好的...我刚刚更改了我的代码：

obj.style.left = wid.toString();

至：

object.style.left = wid.toString()+'px';

它工作得很好
