我有一个以下列方式给出的样式转换字符串：
矩阵(0.312321,-0.949977,0.949977,0.312321,0)
如何形成包含此矩阵元素的数组？有关如何为此编写正则表达式的任何提示？
解决方法
我会这样做的……
- // original string follows exactly this pattern (no spaces at front or back for example)
- var string = "matrix(0.312321,0)";
- // firstly replace one or more (+) word characters (\w) followed by `(` at the start (^) with a `[`
- // then replace the `)` at the end with `]`
- var modified = string.replace(/^\w+\(/,"[").replace(/\)$/,"]");
- // this will leave you with a string: "[0.312321,0]"
- // then parse the new string (in the JSON encoded form of an array) as JSON into a variable
- var array = JSON.parse(modified)
- // check it is correct
- console.log(array)@H_404_11@
