Say I有一系列这样的阵列:
var cars = { vendor: [ { type: [ camry , etc ] } ] }
在 Java中,我用什么指挥手段在类型中添加一个项目...... 例如,如果我希望有一个文本箱,用户可以把案文放在正文中,然后打到一个将该项目添加到阵列的县。 增列的项目必须放在与“运动”和“etc”相同的项目上。 感谢!

类似情况
cars.vendor[0].type.push("foo");
如果“foo”是你的数据,则增加。
您可使用push(

var newValue = 1234;
cars.vendor[0].type.push(newValue);
然后,活动手可以使用类似的东西来约束;
$("yourSelector").on("click", function(){
var value = $("input").val();
cars.vendor[0].type.push(value);
});
抽样 这一问题的例子如下:
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
var cars = {
"vendor": [
{
"type": [
"camry",
"maruti",
"bmw"
]
}
]
};
$("#add").click(function(){
var types=cars["vendor"][0]["type"];
types.push($("#json").val());
$("#types").html(types.toString());
});
});
</script>
</head>
<body>
<input type="text" id="json" name="json"/>
<input type="button" id="add" name="add" value="ADD"/>
<div id="types" style="margin:10px;border:1px dotted green;width:400px;"></div>
</body>
</html>
您可以尝试如下内容:
var cars = { vendor: [ { type: [ camry , etc ] } ] } ;
cars.vendor[0].type[2]="abc";
