$(document).ready(function() {
    // #login-box password field
    $('#password').attr('type', 'text');
    $('#password').val('Password');
});

这是为了将password类型的#password输入字段(id="password")更改为普通的文本字段,然后填充文本"password"。

但这并不奏效。为什么?

表格如下:

<form enctype="application/x-www-form-urlencoded" method="post" action="/auth/sign-in">
  <ol>
    <li>
      <div class="element">
        <input type="text" name="username" id="username" value="Prihlasovacie meno" class="input-text" />
      </div>
    </li>
    <li>
      <div class="element">
        <input type="password" name="password" id="password" value="" class="input-text" />
      </div>
    </li>
    <li class="button">
      <div class="button">
        <input type="submit" name="sign_in" id="sign_in" value="Prihlásiť" class="input-submit" />
      </div>
    </li>
  </ol>
</form>

这对我很管用。

$('#newpassword_field').attr("type", 'text');

我猜你可以使用一个包含单词“password”的background-image,并在.focus()上将其更改为空的background-image。

.blur() ----> image with "password"

.focus() ----->图像没有“密码”

你也可以用一些CSS和jQuery来实现。有一个文本字段显示在密码字段的顶部,hide()是在focus()和聚焦在密码字段…

我还没有在IE中测试(因为我需要这个用于iPad站点)-一个我不能改变HTML但我可以添加JS的表单:

document.getElementById('phonenumber').type = 'tel';

(和jQuery比起来,老派JS太丑了!)

但是,http://bugs.jquery.com/ticket/1957链接到MSDN:“在Microsoft Internet Explorer 5中,type属性是读/写一次的,但仅在使用createElement方法创建输入元素时,并且在将其添加到文档之前。”所以也许你可以复制元素,改变类型,添加到DOM并删除旧的元素?

我已经创建了一个jQuery扩展之间切换文本和密码。适用于IE8(可能也适用于ie6和ie7,但没有测试),不会丢失你的值或属性:

$.fn.togglePassword = function (showPass) {
    return this.each(function () {
        var $this = $(this);
        if ($this.attr('type') == 'text' || $this.attr('type') == 'password') {
            var clone = null;
            if((showPass == null && ($this.attr('type') == 'text')) || (showPass != null && !showPass)) {
                clone = $('<input type="password" />');
            }else if((showPass == null && ($this.attr('type') == 'password')) || (showPass != null && showPass)){
                clone = $('<input type="text" />');
            }
            $.each($this.prop("attributes"), function() {
                if(this.name != 'type') {
                    clone.attr(this.name, this.value);
                }
            });
            clone.val($this.val());
            $this.replaceWith(clone);
        }
    });
};

效果非常好。你可以简单地调用$('#element').togglePassword();在两者之间切换或给出一个选项来“强制”基于其他东西(如复选框)的动作:$('#element').togglePassword($checkbox.prop('checked'));

这里有一个DOM解决方案

myInput=document.getElementById("myinput");
oldHtml=myInput.outerHTML;
text=myInput.value;
newHtml=oldHtml.replace("password","text");
myInput.outerHTML=newHtml;
myInput=document.getElementById("myinput");
myInput.value=text;

Here is a method which uses an image next to the password field to toggle between seeing the password (text input) and not seeing it (password input). I use an "open eye" and "closed eye" image, but you can use whatever suits you. The way it works is having two inputs/images and upon clicking the image, the value is copied from the visible input to the hidden one, and then their visibility is swapped. Unlike many of the other answers which use hardcoded names, this one is general enough to use it multiple times on a page. It also degrades gracefully if JavaScript is unavailable.

这是其中两个在一页上的样子。在这个例子中,密码a是通过点击它的眼睛来显示的。

$(document).ready(function() { $('img.eye').show(); $('span.pnt').on('click', 'img', function() { var self = $(this); var myinp = self.prev(); var myspan = self.parent(); var mypnt = myspan.parent(); var otspan = mypnt.children().not(myspan); var otinp = otspan.children().first(); otinp.val(myinp.val()); myspan.hide(); otspan.show(); }); }); img.eye { vertical-align: middle; } <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <form> <b>Password-A:</b> <span class="pnt"> <span> <input type="password" name="passa"> <img src="eye-open.png" class="eye" alt="O" style="display:none"> </span> <span style="display:none"> <input type="text"> <img src="eye-closed.png" class="eye" alt="*"> </span> </span> </form> <form> <b>Password-B:</b> <span class="pnt"> <span> <input type="password" name="passb"> <img src="eye-open.png" class="eye" alt="O" style="display:none"> </span> <span style="display:none"> <input type="text"> <img src="eye-closed.png" class="eye" alt="*"> </span> </span> </form>
