How to send search text to findInPage in Electron - electron

Question

I try using contents.findInPage.
I have code in index.js:
const { webContents } = require('electron')
webContents.on('found-in-page', (event, result) => {
if (result.finalUpdate) webContents.stopFindInPage('clearSelection')
})
const requestId = webContents.findInPage('api')
console.log(requestId)
And code in component:
searchText(value){
this.query = value;
if (this.query.length > 0) {
ipcRenderer.send('api', this.query);
}
}
I wrote this code on the example of this answer.
But function find not work. I do not understand how I can send the text to be searched and the word to be searched.
How I can use function findInPage ?

Answer 1

sorry my answer to the other question wasn't clear enough (it was 2 years ago! I don't remember it that well but I'll give it a shot)
This is the documentation for webcontents and IPCMain
Here's what I have in my main.development.js (globals for the mainWindow and ipc communication):
mainWindow.on('focus', () => {
globalShortcut.register('CmdorCtrl+F', () => {
mainWindow.webContents.send('find_request', '');
});
});
mainWindow.webContents.on('found-in-page', (event, result) => {
if (result.finalUpdate) {
mainWindow.webContents.stopFindInPage('keepSelection');
}
});
ipcMain.on('search-text', (event, arg) => {
mainWindow.webContents.findInPage(arg);
});
mainWindow.on('blur', () => {
globalShortcut.unregister('CmdorCtrl+F');
});
Then I made an ipc listener for CmdorCtrl+F:
ipcRenderer.on('find_request', () => {
const modalbox = document.getElementById('modalbox');
if (modalbox.style.display === 'block') {
modalbox.style.display = 'none';
} else {
modalbox.style.display = 'block';
}
});
Then I made a modal searchbox:
const searchBox = (
<div
id="modalbox"
style={{ display: 'none', position: 'fixed', zIndex: 1 }}
><input type="text" onChange={Calls.searchPage} />
</div>);
The onchange sends the input text to the ipc listener:
static searchPage(event) {
ipcRenderer.send('search-text', event.target.value);
}
I hope this is enough for you to get it fixed :)
