I'm trying to achieve something similar to what JSRender does, but I'm not sure how to go about it. Consider the HTML "template" below:
<!DOCTYPE html>
<body>
<div class="content">
<div class="notifications">{{:notifications}} notifications</div>
<div class="something else">this is {{:something_else}} to show</div>
</div>
</body>
</html>
Supposed I have JSON data like so:
{"notifications": "3", "something_else": "some arbitrary data"}
How do I populated this data into the HTML page? The way JSRender does it seems to involve creating a separate template in a <script>
tag, then populating the data into the template and finally copying the template into an empty container. Is there a way to avoid this template redefinition? I believe my HTML page can already act like a template as demonstrated above.
The Question: is it possible to display JSON data into a ready HTML page (such as above) with defined "data positions"? As part of the challenge, using $('.notifications').html()
-related methods should be avoided since this would be cumbersome when handling large extensive data.
You can do that using top-level JsViews top-level data-linking - with an element such as a <span>
for each insertion point.
<div class="content">
<div >this is <span data-link="something_else></span> to show</div>
...
Code:
$.link(true, ".content", data);
In addition, the data is data-bound to the HTML.
Here is a sample which shows the data-binding by letting you actually change a data property dynamically:
It also shows data-linking to the src and title attributes of an <img>
tag. See here for more information about different data-link targets.
var data = {notifications: "3", something_else: "some arbitrary data",
imgData: {img1: {src: "http://www.jsviews.com//icons/android-chrome-36x36.png",
desc: "some image"}}};
$.link(true, ".content", data, {replace: true});
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jsviews/0.9.90/jsviews.js"></script>
<div class="content">
<div ><span data-link="notifications"></span> notifications</div>
<div >this is <span data-link="something_else"></span> to show</div>
<img data-link="src{:imgData.img1.src} title{:imgData.img1.desc}"/>
<br/>Edit: <input data-link="something_else"/>
</div>
