我需要一些支持。我有一个数组:
var imageArr = [
{ someobject: '..', anotherobject: '..', img: 'SourceOfFirstImg.jpg'},
{ someobject: '..', anotherobject: '..', img: 'SourceOfSecondImg.jpg'},
// 100 times
]
我想要做的是创建一个.each()
函数来创建<img>
元素,用每个链接src填充它们并将它们附加到div。如果有一个简单的JS方式,我也不需要each()
。
我该怎么做?

您可以使用map
method创建要追加的图像元素数组:
$('.somediv').append($.map(imageArr, function(o){
return $('<img>', { src: o.img });
}));

var imageArr = [
{ someobject: '..', anotherobject: '..', img: 'SourceOfFirstImg.jpg'},
{ someobject: '..', anotherobject: '..', img: 'SourceOfSecondImg.jpg'},
// 100 times
]
for (var i = 0; i < imageArr.length; i++) {
var img = $('<img class="foo" >');
img.attr('src', imageArr[i].img);
$('body').append(img);
};

最简单的,我建议:
var imageArray = [{
'alt': 'Alt text',
'src': 'http://placekitten.com/200/200',
'title': 'Title text'
}, {
'alt': 'More alt text',
'src': 'http://lorempixel.com/200/200',
'title': 'Yet another title attribute'
}],
target = document.body,
img;
imageArray.forEach(function(a){
img = document.createElement('img');
for (var prop in a) {
if (a.hasOwnProperty(prop)) {
img[prop] = a[prop];
}
}
target.appendChild(img);
});
已编辑以使用已发布的imageArr
OP
var imageArr = [{
someobject: '..',
anotherobject: '..',
img: 'SourceOfFirstImg.jpg'
}, {
someobject: '..',
anotherobject: '..',
img: 'SourceOfSecondImg.jpg'
}],
target = document.body,
img;
imageArr.forEach(function (a) {
img = document.createElement('img');
img.src = a.img;
target.appendChild(img);
});

试试这个:
var imageArr = [
{ someobject: '..', anotherobject: '..', img: 'http://www.clipartbest.com/cliparts/Rcd/K5B/RcdK5Bbgi.png'},
{ someobject: '..', anotherobject: '..', img: 'http://www.clipartbest.com/cliparts/Rcd/K5B/RcdK5Bbgi.png'},
]
var div = document.createElement("div");
for(i = 0; i< imageArr.length; i++)
{
var img = document.createElement("img");
img.setAttribute("src",imageArr[i].img);
div.appendChild(img);
}
alert(div.innerHTML);
