Javascript/将CSS样式字符串转换为JS对象 [英] Javascript / convert CSS style string into JS object

问题描述

我们想将以字符串形式输入的CSS样式转换为JS对象.

We'd like to convert a CSS style entered as string into a JS object.

例如

 var input = " border:solid 1px; color:red ";

预期的JS对象:

 {
    border:"solid 1px",
    color:"red"
 }

当然，样式条目的数目以及样式的名称(边框，颜色，字体，z-index等)是不受限制的.谢谢.

Of course the number of style entries is unlimited as well as the names of style (border, color, font, z-index, etc...). Thx.

推荐答案

您可以使用JavaScript拆分功能:

You could use the Javascript split function: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/split

首先用; 作为分隔符分割字符串，然后对于每个用:分割的结果，将项目随心放置在对象中.

First split the string with ; as the separator, and then for each result split with :, placing the items in an object as you go.

例如

var result = {},
    attributes = input.split(';');

for (var i = 0; i < attributes.length; i++) {
    var entry = attributes[i].split(':');
    result[entry.splice(0,1)[0]] = entry.join(':');
}
