在 HTML 中顯示數(shù)據(jù)
w3.displayObject(selector)
易于使用的
只需在任何 HTML 元素中添加括號 {{ }}，就可以為數(shù)據(jù)保留空間:
<div id="id01">{{firstName}} {{lastName}}</div>
最后調(diào)用 w3.displayObject 去顯示數(shù)據(jù)在你的 HTML:
實(shí)例
<script>
var myObject = {"firstName" : "John", "lastName" : "Doe"};
w3.displayObject("id01", myObject);
</script>
var myObject = {"firstName" : "John", "lastName" : "Doe"};
w3.displayObject("id01", myObject);
</script>
嘗試一下 ?
第一個參數(shù)是要使用的HTML元素的id (id01)。
第二個參數(shù)是要顯示的數(shù)據(jù)對象(myObject)。
顯示較大的對象
來演示 W3 的強(qiáng)大功能。JS，我們將顯示一個更大的 JavaScript 對象 (myObject)。
該對象是一個用戶對象數(shù)組，具有 CustomerName、城市和國家屬性:
我的對象
var myObject = {"customers":[
{"CustomerName":"Alfreds Futterkiste","City":"Berlin","Country":"Germany"},
{"CustomerName":"Around the Horn","City":"London","Country":"UK"},
{"CustomerName":"B's Beverages","City":"London","Country":"UK"},
{"CustomerName":"Blauer See Delikatessen","City":"Mannheim","Country":"Germany"},
{"CustomerName":"Bon app'","City":"Marseille","Country":"France"},
{"CustomerName":"Bottom-Dollar Marketse","City":"Tsawassen","Country":"Canada"},
{"CustomerName":"Chop-suey Chinese","City":"Bern","Country":"Switzerland"}
]};
{"CustomerName":"Alfreds Futterkiste","City":"Berlin","Country":"Germany"},
{"CustomerName":"Around the Horn","City":"London","Country":"UK"},
{"CustomerName":"B's Beverages","City":"London","Country":"UK"},
{"CustomerName":"Blauer See Delikatessen","City":"Mannheim","Country":"Germany"},
{"CustomerName":"Bon app'","City":"Marseille","Country":"France"},
{"CustomerName":"Bottom-Dollar Marketse","City":"Tsawassen","Country":"Canada"},
{"CustomerName":"Chop-suey Chinese","City":"Bern","Country":"Switzerland"}
]};
填充下拉列表
實(shí)例
<select id="id01"><option w3-repeat="customers">{{CustomerName}}</option></select>
<script>w3.displayObject("id01", myObject);</script>
<script>w3.displayObject("id01", myObject);</script>
嘗試一下 ? 添加上CSS ?
填充列表
實(shí)例
<ul id="id01"><li w3-repeat="customers">{{CustomerName}}</li></ul>
<script>w3.displayObject("id01", myObject);</script>
<script>w3.displayObject("id01", myObject);</script>

綜合 w3.displayObject 和 w3.includeHTML
在 web 頁面中包含 HTML 片段時，必須確保在正確包含 HTML 之前不會執(zhí)行依賴于所包含 HTML 的其他函數(shù)。
“保留”代碼的最簡單方法是將其放在回調(diào)函數(shù)中。
可以在 w3.includeHTML() 中添加回調(diào)函數(shù)作為參數(shù):
填充復(fù)選框
填充類
填充表格
填充<select>元素
