通过变量在div的样式标签中设置宽度和高度值 [英] Setting the width and heights value in div's style tag from variables

问题描述

在我的javascript文件中，以下行:

In my javascript file I have the following line:

<div id="mygraph" style="width:200px;height:100px;"></div>

我想通过两个变量来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:

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:

var my_width = getWidth();
var my_height = getHeight();

我该怎么做?我缺少正确的语法.预先谢谢你...

How can I accomplish that? I'm missing the correct syntax. Thank you in advance...

推荐答案

以下假设您的函数返回的 my_height 和 my_width 是纯数字:

The following assumes that my_height and my_width returned by your functions are plain numbers:

document.getElementById('mygraph').style.height = my_height + "px";
document.getElementById('mygraph').style.width = my_width + "px";
