compare 2 json对象返回一个包含所有差异的数组

Posted 2021-02-25

pass in 2 json objects returns an array of all differences included those nested in children.

_Q used internally to pass through to self, do not pass in _Q

var compare = function (obj1, obj2, _Q){
		_Q = (_Q == undefined)? new Array : _Q;
 
		function size(obj) {
	        var size = 0;
	        for (var keyName in obj){
	        	if(keyName != null) size++;
	        }
	        return size;
	    };
 
		if (size(obj1) != size(obj2)) {
			//console.log('JSON compare - size not equal > '+keyName)
		};
 
		var newO2 = jQuery.extend(true, {}, obj2);
 
	    for(var keyName in obj1){
	        var value1 = obj1[keyName],
	        	value2 = obj2[keyName];
 
			delete newO2[keyName];
 
			if (typeof value1 != typeof value2 && value2 == undefined) {
				_Q.push(['missing', keyName, value1, value2, obj1])
			}else if (typeof value1 != typeof value2) {
				_Q.push(['diffType', keyName, value1, value2, obj1])
			}else{
		        // For jQuery objects:
		        if (value1 && value1.length && (value1[0] !== undefined && value1[0].tagName)) {
					if (!value2 || value2.length != value1.length || !value2[0].tagName || value2[0].tagName != value1[0].tagName) {
						_Q.push(['diffJqueryObj', keyName, value1, value2, obj1])
					}
				}else if(value1 && value1.length && (value1.tagName !== value2.tagName)){
					_Q.push(['diffhtmlObj', keyName, value1, value2, obj1])
				}else if (typeof value1 == 'function' || typeof value2 == 'function') {
					_Q.push(['function', keyName, value1, value2, obj1])
				}else if(typeof value1 == 'object'){
					var equal = Arcadia.Utility.CompareJson(value1, value2, _Q);
				}else if (value1 != value2) {
					_Q.push(['diffValue', keyName, value1, value2, obj1])
				}
			};
	    }
 
		for(var keyName in newO2){
			_Q.push(['new', keyName, obj1[keyName], newO2[keyName], newO2])
		}
 
		/*
	    */
		return _Q;
	}; // END compare()
