[英]Javascript Regex multiple group matches in pattern
I have a question for a Javascript regex ninja: How could I simplify my variable creation from a string using regex grouping? 我有一个关于Javascript正则表达式忍者的问题:如何使用正则表达式分组从字符串中简化变量创建? I currently have it working without using any grouping, but I would love to see a better way!
我目前没有使用任何分组工作,但我希望看到更好的方式!
The string is: 字符串是:
var url = 'resources/css/main.css?detect=#information{width:300px;}';
The code that works is: 有效的代码是:
var styleStr = /[^=]+$/.exec(url).toString();
var id = /[^\#][^\{]+/.exec(styleStr).toString();
var property = /[^\{]+/.exec(/[^\#\w][^\:]+/.exec(styleStr)).toString();
var value = /[^\:]+/.exec(/[^\#\w\{][^\:]+[^\;\}]/.exec(styleStr)).toString();
This gives: 这给出了:
alert(id) //information
alert(property) //width
alert(value) //300px
Any takers? 任何接受者?
Sure.. 当然..
var url = 'resources/css/main.css?detect=#information{width:300px;}';
var matches = url.match(/#([^{]+){([^:]+):([^;]+)/);
var id = matches[1];
var property = matches[2];
var value = matches[3];
#(?<type>.+){(?<property>.*?):(?<value>.*?);
Group "type": information 31 11
Group "property": width 43 5
Group "value": 300px
