var a=[1,2,3];
var b=[5,6,7];
b=b.concat(a);
console.log(b);
输出结果:[1,2,3,5,6,7]
iE不支持使用assign可以使用var obj = jQuery.extend(formconfig2,data);来代替
或者可以添加以下代码
if (typeof Object.assign != 'function') {
Object.assign = function(target) {
'use strict';
if (target == null) {
throw new TypeError('Cannot convert undefined or null to object');
}
target = Object(target);
for (var index = 1; index < arguments.length; index++) {
var source = arguments[index];
if (source != null) {
for (var key in source) {
if (Object.prototype.hasOwnProperty.call(source, key)) {
target[key] = source[key];
}
}
}
}
return target;
};
}
var obj = Object.assign(formconfig2,data);
