使用jQuery加载进度条的iframe? [英] Iframes loading with progress bar using jQuery?
问题描述
在我的工作(内联网) - 我有一个aspx页面,其中有许多iframe(我们所有的)。
每个iframe都被设置(js / jquery) btnX(在aspx页面中有很多按钮...一些将iframe设置为src - 有些不是)。
注意:progrssBAr位于主页面上...
em>goal:progressBar while iframe is loading ...
code:
(at首先 myPageWrapper
是 display:none
)
<$ p $ ('load','iframe',function(){$(#myProgressBar)。hide();});
<2>问题:
显示
ProgfressBar?
i不想编辑所有btn的事件onclick - 是否有任何集中式解决方案[使用jquery]?
我需要这样做:
$ b 当btn将
src
设置为iframe时 - 显示 myProgressBar
$ b
- 同时发生的事件:iframe A 正在加载2分钟(示例) - 所以它显示进度条,同时我按下其他按钮,将
src
设置为iframe B - 加载速度非常快......一旦加载它,它隐藏ProgressBar(查看我的代码) - 但它不应该... A 尚未完成....
代码更新
- 注意:
由于我收到3张最高票数,我假设这段代码正在帮助别人, ;所以我决定更新代码以反映开始时的意图,因为到目前为止OP已经发现他的问题在他的代码中的其他地方。

主页头
var iframes = [],进度= 0;
$(function(){
$ pGressIndex = $('#progress-bar-indicator');
$('#navigation a')。click(function(){
var iframe_id = this.hash.split('#')[1];
if(iframes.indexOf(iframe_id)=== -1){
$('#log')。prepend('< p>< strong> + iframe_id +'< / strong>正在加载!< / p>');
iframes.push(iframe_id);
if(parseInt($ pGressIndex.width())== 960){
$ pGressIndex.removeAttr('style'); $ b $ (660 - (20 * iframes.length)):660;
$ pGressIndex.animate({b}}
var fW =(iframes.length> 1)
width:fW
},5000);
var iframe_page = iframe_id +'.html';
if($(this.hash).length!= 0){
$(this.hash).remove();
$ b $('< iframe>')。attr({
id:iframe_id,
src:iframe_page,
frameBorder:0,
width:960
})。appendTo('#iframes-wrapper');
}
返回false;
});
});
主页底部:
window.addEventListener(message,function(e){
console.log(iframes);
var index = iframes.indexOf(e.data);
iframes.splice(index,1);
if(iframes.length == 0){
$ pGressIndex.stop(true).animate({
width:960
},100);
}
$('#'+ e.data).show();
},false);
每个iframe页面的底部:
top.postMessage('frame-name-or-what-you-want',window.location.href);
in my job (intranet)- I have an aspx page which has many Iframes ( all ours).
each iframe is being set(js/jquery) by btnX ( there are many buttons in the aspx page... some set src to iframes - some not).
notice : the progrssBAr is on the main page...
goal : progressBar while iframe is loading...
code :
( at first the myPageWrapper
is display:none
)
$('#myPageWrapper').on ('load','iframe',function () { $("#myProgressBar").hide();});
2 problems :
- i can listen to the iframes load finish event. but what about
showing
the ProgfressBar ? i dont want to edit all btn's event "onclick" - is there any centralized solution to this [using jquery]?
i need something that does :
"when btn sets the src
to an iframe - show myProgressBar
"
- simultaneous events can occur : iframe A is being loading for 2 min ( example) - so it shows the progress bar , meanwhile i pressed other button which sets
src
to iframe B - which is loading very fast... once its loaded - it hides the ProgressBar ( look at my code) - but it shouldnt...A didnt finish yet....
CODE UPDATED
- NOTE:
since i received 3 up-votes i assume that this code is helping someone else other then the original OP; so i decided to update the code to reflect what it was meant to be at the beginning, since so far the OP and i have discovered that his problem was somewhere else in his code.

head of main page
var iframes = [], progress = 0;
$(function() {
$pGressIndex = $('#progress-bar-indicator');
$('#navigation a').click(function() {
var iframe_id = this.hash.split('#')[1];
if (iframes.indexOf(iframe_id) === -1) {
$('#log').prepend('<p><strong>' + iframe_id + '</strong> is loading!</p>');
iframes.push(iframe_id);
if (parseInt($pGressIndex.width()) == 960) {
$pGressIndex.removeAttr('style');
}
var fW = (iframes.length > 1) ? (660 - (20 * iframes.length ) ) : 660;
$pGressIndex.animate({
width : fW
}, 5000);
var iframe_page = iframe_id + '.html';
if ($(this.hash).length != 0) {
$(this.hash).remove();
}
$('<iframe>').attr({
id : iframe_id,
src : iframe_page,
frameBorder : 0,
width : 960
}).appendTo('#iframes-wrapper');
}
return false;
});
});
bottom of main page:
window.addEventListener("message", function(e) {
console.log(iframes);
var index = iframes.indexOf(e.data);
iframes.splice(index, 1);
if (iframes.length == 0) {
$pGressIndex.stop(true).animate({
width : 960
}, 100);
}
$('#' + e.data).show();
}, false);
bottom of each iframe page:
top.postMessage('frame-name-or-what-you-want', window.location.href);
