jQuery在字符串中查找模式

Question

I need to find path information from a string using jquery and push the results into an array.

The string output looks like;

 "var rsr = Raphael('rsr', '270', '266'); 
 var path_a = rsr.path('M144.869,199c0,7.659-5.479,13.139-13.14,
 13.139 c-7.659,0-14.598-5.479-14.598-13.139s6.209-13.139,13.869-
 13.139S144.869,191.341,144.869,199z'); path_a.attr({fill: 'non .... etc" 

I need to retrieve every occurrence of the path information with in rsr.path() ;

How would i go about achieving this? using $.each on my string with a regex?

thanks cam

Answer 1

JavaScript will let you do this with a regular expression:

var s = " var rsr = Raphael('rsr', '270', '266'); var path_a = rsr.path('M144.869,199c0,7.659-5.479,13.139-13.14, 13.139 c-7.659,0-14.598-5.479-14.598-13.139s6.209-13.139,13.869- 13.139S144.869,191.341,144.869,199z'); path_a.attr({fill: 'non .... etc";

var regex = /M144\.869(.+?)869,199z/g;
var matches = regex.exec(s);

matches[0] then contains the capture group.

i found this worked..

 $(document).ready(function(){

    $('form.svg-convert').submit(function(event){

        var content = $(this).find('textarea').val();
        process(content);

        event.preventDefault();
    })
})


var process = function(c){

    var content = c,
        paths = [];

    var contentSplit = content.split('path(');
    contentSplit.shift(); 

    $.each(contentSplit,function(i,v){

        var path = v.split(')');
        path = path[0];
        paths.push(path);

    });

}
