输入框去空格,

<script type="text/javascript">
function Trim(obj,str,is_global){
            var result;
            result = str.replace(/(^s+)|(s+$)/g,"");
            if(is_global.toLowerCase()=="all")
            {
                result = result.replace(/s/g,"");
             }
            $(obj).val(result);
}

</script>

调用:当第三个参数为小写all的时候去除前后中间空格,否则只去除首尾空格

<input type="text" onblur="Trim(this,this.value,'all')" value="">
