站長資訊網(wǎng)username1: “(^[a-zA-Z]{1}([a-zA-Z0-9_]){4,14}|(^[u4E00-uFA29]{1}+[a-zA-Z0-9u4E00-uFA29]{2,7}))$”,
復制代碼 代碼如下:
<script>
<!–
function checkStr(str){
// [u4E00-uFA29]|[uE7C7-uE7F3]漢字編碼范圍
var re1 = new RegExp(“^([u4E00-uFA29]|[uE7C7-uE7F3]|[a-zA-Z0-9])*$”);
if (!re1.test(str)){
alert(“否”);
return false;
}
alert(“是”);
return true;
}
//–>
</script>
