I am loading a local html file as the src for a NativeScript WebView component. Contained within the html file are script tags which reference javascript files that are also local resources (bundled within the app). The html file loads into the WebView just fine, but the referenced script file (mylib.js) does not.
I suspect a pathing problem but I have tried almost every variation I can think of to no avail.
My project is actually a NativeScript-Vue project and is as follows:
App.vue
<template>
<Page @loaded="onPageLoaded">
<ActionBar title="Welcome to WebView"/>
<GridLayout>
<WebView ref="myWebView" row="0" col="0"
:src="filePath" @loadFinished="onWebViewLoaded" />
</GridLayout>
</Page>
</template>
<script>
import * as fs from "tns-core-modules/file-system"
import * as utils from "utils/utils"
export default {
data() {
return {
filePath: ''
}
},
methods: {
onPageLoaded () {
this.setLocalIndexFilePath()
},
onWebViewLoaded (event) {
if (event.error) {
console.log(error)
} else {
console.log('webview loaded')
}
},
setLocalIndexFilePath () {
const deviceName =
utils.ios.getter(UIDevice, UIDevice.currentDevice).name
// iPhone 6 is the name of my simulator
if (deviceName == 'iPhone 6') {
const webViewSRC =
encodeURI(`${fs.knownFolders.currentApp().path}/www/index.html`)
this.filePath = webViewSRC
console.log(webViewSRC)
} else {
this.filePath = "~/www/index.html"
}
}
}
}
</script>
index.html
<!doctype html>
<head>
<script src="./mylib.js" type="text/javascript"></script>
<script type="text/javascript">
function onBodyLoaded() {
var msg = document.getElementById('msg');
msg.insertAdjacentHTML('beforeend', '<br />body loaded!');
}
function onLocalButtonClicked() {
var msg = document.getElementById('msg');
msg.insertAdjacentHTML('beforeend', '<br />local: You clicked button!');
}
</script>
</head>
<html>
<body onload="onBodyLoaded()">
<Button onclick="onLocalButtonClicked()">Click Me</Button>
<Button onclick="onButtonClicked()">Click Me to test external js</Button>
<p id="msg">Debug:</p>
</body>
</html>
mylib.js
// This function never gets called
function onButtonClicked() {
var msg = document.getElementById('msg');
msg.insertAdjacentHTML('beforeend', '<br />external js file: You clicked button!');
}
