仅在完全加载后显示所有图像 [英] Show all images only after their complete load

问题描述

在

<div id="all-images">
    <img src="images/1.jpg">
    <img src="images/2.jpg">
    <img src="images/3.jpg">
    <img src="images/4.jpg">
    <img src="images/5.jpg">
    <img src="images/6.jpg">
</div>

仅当此ID中的所有图像都将完全加载(jQuery)时，我才想显示id ="all-images"的所有图像.

I want to show all Images of id="all-images" only when all the images inside this id will load completely (Jquery).

在加载所有图像之前，此部分显示正在加载.."文本

And before loading all images this section shows "Loading.." text

推荐答案

假设您的div已被预先隐藏:

Assuming your div is pre-hidden:

$("#loadingDiv").show();
var nImages = $("#all-images").length;
var loadCounter = 0;
//binds onload event listner to images
$("#all-images img").on("load", function() {
    loadCounter++;
    if(nImages == loadCounter) {
        $(this).parent().show();
        $("#loadingDiv").hide();
    }
}).each(function() {

    // attempt to defeat cases where load event does not fire
    // on cached images
    if(this.complete) $(this).trigger("load");
});
