Cara menggunakan:

<input type="text" class="reg_txt" value="身份证号" titles="请输入您的身份证号!" name="userid" id="username" maxlength="40" onfocus="if(this.value=='身份证号'){this.value='';}" onblur="if(this.value==''){this.value='身份证号';}nunber(this.value);" style="border: 1px solid red;"><br> 
<span class="c_red" id="span_username"></span> 

Salin selepas log masuk

Kesannya ialah memasukkan nombor ID, mengesahkannya secara automatik selepas fokus dialih keluar, dan mengembalikan maklumat!
