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;
}
