jQuery UI效果导致iframe重新加载

我正在使用jQuery显示/隐藏碰巧包含iframe的div。它只适用于标准的“show”和“hide”方法。

所以现在我想得到一些幻想,并从jQuery UI(http://jqueryui.com/effect/)添加一些效果,但突然我的iframe每次显示/隐藏时都会重新加载。

这是一个演示的小提琴:http://jsfiddle.net/BnZzk/1/ 这是代码,因为SO迫使我添加它:

<style>
div {
    height: 200px
}
span {
    display: block;
    padding-bottom: 10px;
    margin-bottom: 10px;
    border-bottom: 1px solid black;
}
</style>

<div>
    <iframe src="http://www.wikipedia.org/"></iframe>
</div>
<input type="button" value="Go"/>
<hr/>
<div id="msgs"></div>

<script>
$(function () {

var container = $('div'),
    ifrm = $('iframe'),
    msgs = $('#msgs')
    delay = 10; //change me to adjust delay in seconds between actions

$('input').on('click', normal);
log('First let the iframe load and then clear your network console -- click the "Go" button to get started.');

function log (msg) {
    msgs.append('<span>' + msg + '</span>');
}

function normal () {

    ifrm.
        hide(400, function () {

            log('That was a standard hide with no effect -- is your network console still empty? OK we\'ll pause for ' + delay + ' seconds and then do a standard show.');

            ifrm.
                delay(delay * 1000).
                show(400, function () {
                    log('That was a show with no effect -- is you network console *still* empty? Great! Let\'s try some effects.');
                    log('------------------------<br/>' +
                    '-- Begin Effects --<br/>' +
                    '------------------------<br/>');
                    withEffect();
                });

        }); //hide

} //normal

function withEffect () {

    log('We\'ll pause for another ' + delay + ' seconds -- get ready to watch your network console.');

    ifrm.
        delay(delay * 1000).
        hide('fold', {mode:'hide'}, 400, function () {

            log('That was a hide with effect -- is your network console flooded? Mine too :-( We\'ll wait ' + delay + ' seconds while you clear your console again.');

            ifrm.
                delay(delay * 1000).
                show('fold', {mode:'show'}, 400, function () {
                    log('That was a show with effect -- is your network console flooded again? Bummer ...');
                });

        }); //hide

} //withEffect

});
</<script>

知道如何保持花哨效果但不刷新我的iframe内容吗?

这种情况正在发生,因为这个效果会重新组织DOM,在IFRAME周围放置一个DIV包装器,所以当IFRAME被“重新连接”时,重新加载就会发生!您可以使用Google Chrome元素检查器查看此行为。

要解决我建议您从IFRAME中的父DIV中应用效果,但不使用effect插件。查看http://api.jquery.com/animate/,操纵宽度和高度样式属性。

作为@Jamillo Santos的回答,'重新'关注iFrame问题。

如果您正在使用jQueryUI的对话框小部件或其扩展程序,并希望防止出现这种情况, 只需重新定义您的小部件实现的 _moveToTop()功能,如下所示。

_moveToTop: function() {
    return null;
},
