js to check if two objects are equal

1. First, there must be two objects, the following example:

 var obj1 = {
  name:"xx",
  sex:"man",
  age:18
}

var obj2 = {
  name:"xxs",
  sex:"man",
  age:18
}

2. Determine whether two objects are equal:

 function isObjectValueEqual (a, b) {
    //取对象a和b的属性名
    var aProps = Object.getOwnPropertyNames(a);
    var bProps = Object.getOwnPropertyNames(b);
    //判断属性名的length是否一致
    if (aProps.length != bProps.length) {
        return false;
    }
    //循环取出属性名，再判断属性值是否一致
    for (var i = 0; i < aProps.length; i++) {
        var propName = aProps[i];
        if (a[propName] !== b[propName]) {
            return false;
        }
    }
    return true;
}

3. Make the corresponding operation:

 var isChange = isObjectValueEqual(obj1,obj2);
if (isChange == true){
    console.log('没有修改，不需要提示是否保存');
}else {
    console.log('发生修改，提示是否保存');
}
