javascript - JavaScript window.getComputedStyle

Question

如何将 windows.getComputed 样式作为 int 值？

默认显示方式是字符串：

var style = window.getComputedStyle(elem1, null);
alert(style.top); //Returns a string

Answer 1

parseFloat将为您提供实际值作为保留小数位的数字：

parseFloat(style.top);

Answer 2

parseInt() will return you the String as an Integer, so your code should look somehow like this:

var style = window.getComputedStyle(elem1, null);
alert(parseInt(style.top));
