Object.keys
返回一个所有元素为字符串的数组,其元素来自于从给定的object
上面可直接枚举的属性。这些属性的顺序与手动遍历该对象属性时的一致。
// simple array var arr = ['a', 'b', 'c']; console.log(Object.keys(arr)); // console: ['0', '1', '2'] // array like object var obj = { 0: 'a', 1: 'b', 2: 'c' }; console.log(Object.keys(obj)); // console: ['0', '1', '2'] // array like object with random key ordering var anObj = { 100: 'a', 2: 'b', 7: 'c' }; console.log(Object.keys(anObj)); // console: ['2', '7', '100'] // getFoo is a property which isn't enumerable var myObj = Object.create({}, { getFoo: { value: function () { return this.foo; } } }); myObj.foo = 1; console.log(Object.keys(myObj)); // console: ['foo']
//-------------------------------表单清空
Object.keys(this.formValue).forEach((key) => {
this.formValue[key] = null
})
注:在vue中
this.$refs[formName].resetFields(); //要配合prop才能用
