$(document).ready(function() {
// #login-box password field
$('#password').attr('type', 'text');
$('#password').val('Password');
});
这是为了将password类型的#password输入字段(id="password")更改为普通的文本字段，然后填充文本"password"。
但这并不奏效。为什么?
表格如下:
<form enctype="application/x-www-form-urlencoded" method="post" action="/auth/sign-in">
<ol>
<li>
<div class="element">
<input type="text" name="username" id="username" value="Prihlasovacie meno" class="input-text" />
</div>
</li>
<li>
<div class="element">
<input type="password" name="password" id="password" value="" class="input-text" />
</div>
</li>
<li class="button">
<div class="button">
<input type="submit" name="sign_in" id="sign_in" value="Prihlásiť" class="input-submit" />
</div>
</li>
</ol>
</form>
这样就可以了。尽管可以改进为忽略现在不相关的属性。
插件:
(function($){
$.fn.changeType = function(type) {
return this.each(function(i, elm) {
var newElm = $("<input type=\""+type+"\" />");
for(var iAttr = 0; iAttr < elm.attributes.length; iAttr++) {
var attribute = elm.attributes[iAttr].name;
if(attribute === "type") {
continue;
}
newElm.attr(attribute, elm.attributes[iAttr].value);
}
$(elm).replaceWith(newElm);
});
};
})(jQuery);
用法:
$(":submit").changeType("checkbox");

http://jsfiddle.net/joshcomley/yX23U/
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;
}

一个更跨浏览器的解决方案……我希望这篇文章的要点能帮助到一些人。
此解决方案尝试设置type属性，如果失败，则简单地创建一个新的<input>元素，保留元素属性和事件处理程序。
changetypeatr .js (GitHub Gist):
/* x is the <input/> element
type is the type you want to change it to.
jQuery is required and assumed to be the "$" variable */
function changeType(x, type) {
x = $(x);
if(x.prop('type') == type)
return x; //That was easy.
try {
return x.prop('type', type); //Stupid IE security will not allow this
} catch(e) {
//Try re-creating the element (yep... this sucks)
//jQuery has no html() method for the element, so we have to put into a div first
var html = $("<div>").append(x.clone()).html();
var regex = /type=(\")?([^\"\s]+)(\")?/; //matches type=text or type="text"
//If no match, we add the type attribute to the end; otherwise, we replace
var tmp = $(html.match(regex) == null ?
html.replace(">", ' type="' + type + '">') :
html.replace(regex, 'type="' + type + '"') );
//Copy data from old element
tmp.data('type', x.data('type') );
var events = x.data('events');
var cb = function(events) {
return function() {
//Bind all prior events
for(i in events)
{
var y = events[i];
for(j in y)
tmp.bind(i, y[j].handler);
}
}
}(events);
x.replaceWith(tmp);
setTimeout(cb, 10); //Wait a bit to call function
return tmp;
}
}
