密码字段默认值 [英] Password field default value

问题描述

我怎样才能使用HTML密码输入并设置一个文本默认值，因为密码输入会将字符转换为点或星号，因此这些默认值将是可读的？我可以用Javascript来做到这一点吗？

直到有人点击它，这时它会变成空白，并且在那里键入的任何东西都会变成*的？好的，你想要的是这样的：

在头：

 < ; script type =text / javascript> 
 function changefield（）{
 document.getElementById（passwordbox）。innerHTML =< input id = \password-field \type = \password \name = \password-field \title = \Password \/>; 
 document.getElementById（password-field）。focus（）; 
} 
< / script> 
  

在正文中：

 < div id =passwordbox> 
< input id =password-fieldtype =textname =password-fieldtitle =Passwordonfocus =changefield（）; value =password/> 
< / div> 
  

How can I both use the HTML password input and set a text default value that will be readable since the password input will turn the characters into dots or stars? Can I do this with Javascript?

解决方案

So if I understand correctly, you want it to read "password" or whatever in regular letters until someone clicks on it, at which point it will turn blank, and anything typed in there will become *'s? Ok what you want is this:

in head:

<script type="text/javascript">
    function changefield(){
        document.getElementById("passwordbox").innerHTML = "<input id=\"password-field\" type=\"password\" name=\"password-field\" title=\"Password\" />";
        document.getElementById("password-field").focus();
    }
</script>

in the body:

<div id="passwordbox">
<input id="password-field" type="text" name="password-field" title="Password" onfocus="changefield();" value="password" />
</div>
