Display data in HTML
Just add brackets {{ }} to any HTML element to reserve space for your data:
<div id="id01">
{{firstName}} {{lastName}}
</div>
Finally call w3.displayObject to display the data in your HTML:
<script>
var myObject = {"firstName" : "John", "lastName" : "Doe"};
w3.displayObject("id01", myObject);
</script>
The first parameter is the id of the HTML element to use (id01).
The
second parameter is the data object to display (myObject).
To demonstrate the power of W3.JS, we will display a larger JavaScript object (myObject).
The object is an array of customers objects with the CustomerName, City, and Country properties:
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"}
]};
<select id="id01">
<option
w3-repeat="customers">{{CustomerName}}</option>
</select>
<script>
w3.displayObject("id01", myObject);
</script>
<ul id="id01">
<li w3-repeat="customers">{{CustomerName}}</li>
</ul>
<script>
w3.displayObject("id01", myObject);
</script>
When you include HTML snippets in a web page, you must secure that other functions that depend on the included HTML do not execute before the HTML is properly included.
The easiest way to "hold back" code is to place it in a callback function.
A callback function can be added as an argument to w3.includeHTML():
<div w3-include-html="list.html"></div>
<script>
w3.includeHTML(myCallback);
function myCallback() {
w3.displayObject("id01", myObject);
}
</script>
<table id="id01">
<tr w3-repeat="customers">
<td>{{CustomerName}}</td>
<td><input type="checkbox" {{checked}}"></td>
</tr>
</table>
<script>
w3.displayObject("id01", myObject);
</script>
<table id="id01">
<tr w3-repeat="customers" class="{{Color}}">
<td>{{CustomerName}}</td>
</tr>
</table>
<script>
w3.displayObject("id01", myObject);
</script>
<table id="id01">
<tr>
<th>Customer</th>
<th>City</th>
<th>Country</th>
</tr>
<tr w3-repeat="customers">
<td>{{CustomerName}}</td>
<td>{{City}}</td>
<td>{{Country}}</td>
</tr>
</table>
<script>
w3.displayObject("id01", myObject);
</script>
<select id="id01">
<option w3-repeat="x in cars">{{x}}</option>
</select>
<script>
w3.displayObject("id01", {"cars" : ["Volvo", "Ford", "BMW", "Mercedes"]});
</script>
