我不明白爲什麼拼接方法不適合我。我有一個數組,看起來像:(它實際上是更大的,但我不想弄亂頁)插入對象文字到數組中
var navItems = [ {
"content": "Panels",
"icon": "panels"
},
{
"content": "Samples",
"icon": "sample"
}];
我要插入一個項目在中間說:
var testNavItems = navItems.splice(1, 0, {
"content": "New Nav",
"icon": "New Nav"
});
console.log(testNavItems);
OR
var testNavItems = navItems.push({
"content": "New Nav",
"icon": "New Nav"
});
console.log(testNavItems);
我得到一個空的數組。這在JS中可能嗎?
['.splice'](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/splice)返回已元素刪除,['.push'](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/push)返回數組的新長度。始終檢查文檔。 – 2013-03-26 18:43:23
