使用方法:
1 2 | < 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 > |
效果为输入身份证号,焦掉移开后自动验证,并返回信息!
