问题描述
我正在使用YUI DataTables，以填充我想从外部动态发送列及其值的数据表，为此，我编写了以下代码:
I am working on YUI DataTables, to populate the data table i want to send the columns and their values dynamically from outside, for that i have written the following code:
<html>
<script src="http://yui.yahooapis.com/3.17.2/build/yui/yui-min.js"></script>
<div class="example yui3-skin-sam" id="simple"> <!-- You need this skin class -->
</div>
<script>
var cols = ["id", "name", "price"];
var obj = {
id: "",
name: "",
price: ""
};
var data2 = new Array();
obj.id = "ga";
obj.name = "gadget";
obj.price = "$6.99";
data2.push(obj);
obj.id = "ga2";
obj.name = "gadget2";
obj.price = "$7.99";
data2.push(obj);
obj.id = "ga3";
obj.name = "gadget3";
obj.price = "$8.99";
data2.push(obj);
YUI().use("datatable", function (Y) {
// A table from data with keys that work fine as column names
var simple = new Y.DataTable({
columns: cols,
data : data2,
summary: "Price sheet for inventory parts",
caption: "Example table with simple columns"
});
simple.render("#simple");
});
</script>
</html>
现在的问题是，它仅显示data2中推送的最后一个obj.请告诉我为什么它不显示所有三个obj.此代码生成的表是
now the problem is that, it shows only the last obj pushed in data2.. kindly tell me why its not displaying all three objs. the resulting table from this code is
id name price
ga3 gadget3 $8.99
推荐答案
它将给出所有数组值
function obj(id, name, price) {
this.id = id;
this.name = name;
this.price = price;
}
var array = new Array();
var point = new obj("ga", "gadget", "$6.99");
array.push(point);
var point = new obj("ga2", "gadget2", "$7.9");
array.push(point);
