不错，正是所需。
var partten = /^[\u4e00-\u9fa5A-Za-z0-9\_]*$/;
var ary = ["陈小稳2342@#$", "陈小稳abc124dd的_1"];
for(var i=0;i<ary.length;i++){
var str = ary[i];
alert(str+"="+partten.test(str));
}
var partten = /^[\u4e00-\u9fa5A-Za-z0-9\_]*$/;
var ary = ["陈小稳2342@#$", "陈小稳abc124dd的_1"];
for(var i=0;i<ary.length;i++){
var str = ary[i];
alert(str+"="+partten.test(str));
