javascript split掉空格和逗号

// 空白（空格、换行、tab）和逗号分隔的字符串，变成用逗号分隔function getSplitString(str){     var arr = str.split(",");   var resources = "";     for (var i = 0; i < arr.length; i++) {     var arr1 = arr[i].split(/\s+/); for (var j = 0; j < arr1.length; j++) {     if (jQuery.trim(arr1[j]) != "") {     resources += jQuery.trim(arr1[j]) + ","; } } }  return resources;}
