<script type="text/javascript">
// 这里使用最原始的js语法实现，可对应换成jquery语法进行逻辑控制
var demoImg = document.getElementById("demo_img");
var demoInput = document.getElementById("demo_input");
//隐藏text block，显示password block
function hideShowPsw(){
if (demoInput.type == "password") {
demoInput.type = "text";
demo_img.src = "invisible.png";
}else {
demoInput.type = "password";
demo_img.src = "visible.png";
}
