Setting the width and heights value in div's style tag from variables
提问by goseib
In my javascript file I have the following line:
在我的 javascript 文件中，我有以下行：
<div id="mygraph" style="width:200px;height:100px;"></div>
I'd like to set the width and height values in the style tag from two variables that take their values from the corresponding functions:
我想从两个变量中设置样式标签中的宽度和高度值，这些变量从相应的函数中获取它们的值：
var my_width = getWidth();
var my_height = getHeight();
How can I accomplish that? I'm missing the correct syntax. Thank you in advance...
我怎样才能做到这一点？我缺少正确的语法。先感谢您...

The following assumes that my_heightand my_widthreturned by your functions are plain numbers:
以下假设您的函数返回的my_height和my_width是普通数字：
document.getElementById('mygraph').style.height = my_height + "px";
document.getElementById('mygraph').style.width = my_width + "px";
