[英]Using Json to load all images from server, and displaying them Masonry
我想做的是从服务器上的文件夹中获取20张左右的图像,并使用masonry.desandro显示它们,一旦滚动到底部,它将加载另一组20张图像。 就像pinterest。 当前它确实一次加载20个图像,我唯一的问题是前20个显示砌体,但是接下来的20个加载却不显示砌体
的HTML
<div class="grid">
</div>

$(document).ready(function() {
// The max number of images to be loaded at a time.
var limit = 16;
// JSON data will be assigned to this
var images = "";
// to remember where in JSON we are
// initialize to the value of limit - so that we can load in images
// before page scroll.
var currentIndex = limit;
// When there are fewer than `limit` images left, this
// value will be the difference between the current index
// and the length of the images array.
var stop = limit;
var grid = $(".grid");
// Make a GET request to the api
$.getJSON("***********************/newsite/api.php", function(data) {
// save the data to be used later.
images = data.weddingCakes;
console.log(data);
})
// create the first round of images.
.done(function() {
var html = "";
for (var i = 0; i < limit; i++) {
html += '<div class="grid-item"><img src="' + images[i] + '"></div>';
}
grid.append(html)
.masonry({
gutter: 3,
itemSelector: '.grid-item',
animate: true
});
console.log("masonry")
})
.error(function() {
console.log("error");
});
$(document).scroll(function() {
// get the scoll position with support for IE
// see http://jsbin.com/egegu3/6/edit?html,js,output
// for original code.
var totalHeight, currentScroll, visibleHeight;
if (document.documentElement.scrollTop) {
currentScroll = document.documentElement.scrollTop;
} else {
currentScroll = document.body.scrollTop;
}
totalHeight = document.body.offsetHeight;
visibleHeight = document.documentElement.clientHeight;
// only load more images if the scroll bar is at the bottom
$(window).scroll(function() {
if($(window).scrollTop() + $(window).height() == $(document).height()) {
var diff = images.length - currentIndex;
// if the difference is > 0 then there are more images in the array
if (diff > 0) {
stop = diff > limit ? limit : diff;
getImages(currentIndex, stop);
currentIndex += stop;
}
// otherwise, reset the index before calling getImages()
else {
currentIndex = 0;
stop = diff > limit ? limit : diff;
getImages(currentIndex, stop);
currentIndex += stop;
}
}
});
});
// gets the path for each image from index to stop
function getImages(index, stop) {
var html = "";
// create the img tags.
for (var i = index; i < index + stop; i++) {
html += '<div class="grid-item"><img src="' + images[i] + '"></div>';
}
var str = $(html);
grid.append(html).masonry("appended", str);
}
});
我的JSfiddle
您几乎是正确的,只是在阅读文档时错过了一小部分,在这里添加元素时需要添加HTML元素并将其传递给砌筑函数。
您正在添加字符串以追加,后来又将元素传递给砌体,同样,此代码-> var str = $(html); 返回HTML元素而不是字符串的数组,因此您需要将这些元素添加到网格并将其传递给砌体
所以你的零钱是...
// gets the path for each image from index to stop
function getImages(index, stop) {
var html = "";
// create the img tags.
for (var i = index; i < index + stop; i++) {
html += '<div class="grid-item"><img src="' + images[i] + '"></div>';
}
var str = $(html);
grid.append(str).masonry("appended", str); // This line is a change
}
