About Aspose.Font for JavaScript | API for JavaScript

Overview

The Aspose.Font for JavaScript library represents information about engine library name, release version, and licensing status.

How to get information about the library?

Just run the AsposeFontAbout function.
Next, if the json.errorCode is 0, then the result json contains fields product, version, islicensed with info about the library. If the json.errorCode parameter is not equal to 0 then error information will be contained in the json.errorText.

Below is the sample which gets info about the library on load:

 1  var onloadAsposeFontforJS = function () {
 2    var Module_onRuntimeInitialized = Module['onRuntimeInitialized'];
 3    Module['onRuntimeInitialized'] = async function() {
 4        console.log('AsposeFontforJS has loaded');
 5        await Module_onRuntimeInitialized();
 6        //Get info about Product
 7        const json = AsposeFontAbout();
 8        if (json.errorCode == 0) document.getElementById('output').textContent = "Product      : " + json.product
 9                                                                             + "\nVersion      : " + json.version
10                                                                             + "\nIs licensed  : " + json.islicensed;
11        else document.getElementById('output').textContent = json.errorText;
12    }
13  }

or using Web Worker:

 1  /*Create Web Worker*/
 2<script type="text/javascript">
 3  const AsposeFontWebWorker = new Worker("AsposeFontforJS.js");
 4  AsposeFontWebWorker.onerror = evt => console.log(`Error from Web Worker: ${evt.message}`);
 5  AsposeFontWebWorker.onmessage = evt => {
 6	if (evt.data == 'ready')
 7      AsposeFontWebWorker.postMessage({ "operation": 'AsposeFontAbout', "params": [] }, []);
 8	else
 9	  document.getElementById('output').textContent = (evt.data.json.errorCode == 0) ?
10         `Product      : ${evt.data.json.product}`
11     + `\nVersion      : ${evt.data.json.version}`
12     + `\nIs licensed  : ${evt.data.json.islicensed}` :
13        `Error: ${evt.data.json.errorText}`;
14  };
15</script>
