我正在开发一个应用程序,我将图像拖放到网格中,然后在删除后我创建了一个json对象,我将这些拖放图像添加到json对象中,有一个144平方的网格。
我的json对象是通过条目创建的:
27: Object
51: Object
54: Object
75: Object
99: Object
123: Object
125: Object
如何在jquery中循环我的确切键号以与其他json对象匹配?

示例示例:
var arr = [ "one", "two", "three", "four", "five" ];
var obj = { one: 1, two: 2, three: 3, four: 4, five: 5 };
jQuery.each( arr, function( i, val ) {
$( "#" + val ).text( "Mine is " + val + "." );
// Will stop running after "three"
return ( val !== "three" );
});
jQuery.each( obj, function( i, val ) {
$( "#" + i ).append( document.createTextNode( " - " + val ) );
});
输出:
Mine is one. - 1
Mine is two. - 2
Mine is three. - 3
- 4
- 5

你可以像这样循环对象的属性:
var obj = {1: 'val1', 2:'val2', 3:'val3' }
for (var param in obj) {
if (obj.hasOwnProperty(param))
console.log(obj[param])
}
这将打印出来:
val1
val2
val3
