如果对象出现在其他对象中,我试图从对象中删除对象。真的很难exaplin!这是一个例子。我有2个包含DOM图像对象的对象,如果它们出现在第二个对象中,我希望从第一个对象中删除DOM图像对象。
第一个对象
{
"241": [{
"img": image_object_1
},
{
"img": image_object_2
},
{
"img": image_object_3
},
{
"img": image_object_4
}]
}
第二个对象
{
"241": [{
"img": image_object_1
},
{
"img": image_object_3
},
{
"img": image_object_4
}]
}
对象1的预期结果
{
"241": [{
"img": image_object_2
}]
}
我将所有内容都放在一个对象中,但如果需要,我很乐意更改格式
{
"0": {
},
"1": {
"241.14999389648438": [{
"img": {
image_object_1
},
},
{
"img": {
image_object_2
},
},
{
"img": {
image_object_3
},
},
{
"img": {
image_object_4
},
}]
},
"2": {
"241.14999389648438": [{
"img": {
image_object_2
},
},
{
"img": {
image_object_3
},
},
{
"img": {
image_object_4
},
}]
}
}
我的工作代码在这里
jQuery.fn.reverse = [].reverse;
function same_height(){
var imob = {};
var groups = [];
var heights = [];
var tp = 0;
var img = false;
$("#ez-container .row").each(function(gi){
imob = {};
groups[gi] = {};
heights[gi] = {};
tp = 0;
img = false;
$(this).find(".ez-image img").each(function(){
img = $(this);
tp = img.offset().top;
imob = {
"img":img,
"padding":img.outerHeight(true) - (parseInt(img.css('borderBottomWidth'))+parseInt(img.css('borderTopWidth'))) - img.innerHeight()
};
if(typeof(groups[gi][tp])=="undefined"){
groups[gi][tp] = [];
heights[gi][tp] = [];
}
groups[gi][tp].push(imob);
heights[gi][tp].push(img.height());
});
});
heights.reverse();
var max_group_height = 0;
$.each(groups.reverse(),function(gix,grp){
$.each(grp,function(t,im){
if(im.length>1){
$.each(im,function(i,v){
max_group_height = Math.max.apply(Math, heights[gix][t]);
if(typeof(v.img.attr("data-fixed"))=="undefined"){
v.img.css({"height":max_group_height+(v.padding)+"px"}).attr("data-height",0).attr("data-width",0).attr("data-fixed",1);
}
});
}
});
});
do_swap_images();
}
答案 0 :(得分:0)
如果您检查dom图像节点,则需要isSameNode个功能。我不确定您的要求,希望下面的代码有帮助
//suppose a, b are your objects
var key = 241
var diff = a[key].filter( function( v ){
var firstImgNode = v.img;
return !b[key].some( function( v ){
return v.img.isSameNode( firstImgNode );
});
});
或者如果您检查其他数据类型,则只需执行v.img == firstImgNode
