github.com/zserge/lorca library allows you to bind go funcs to javascript through chrome's dev protocol. With this, you can pass arguments into a go func from the browser.
I'm trying to submit HTML directly to a go func instead of using an embedded http server due to development requirements. (Please don't go off topic & ask why not use a server.)
Here's an example of what I can do:
var inputform string = `
<html>
<body>
<form action="/action_page.php">
<input type="text" name="userinput">
<input type="submit" onclick="golangfunc(userinput.value)">
</form>
</body>
</html>
`
func main(){
ui, err := lorca.New("data:text/html,"+url.PathEscape(inputform), "", 480, 320)
ui.Bind("golangfunc", golangfunc)
defer ui.Close()
<-ui.Done()
}
func golangfunc(input string){
fmt.Println(input)
}
I have an arbitrary number of HTML input fields, and so I'd like to pass an HTML form instead of a single input value, but not sure how to do this.
github.com/zserge/lorca supported JS function from Go. Get HTML Form Elements using ui.eval.
package main
import (
"fmt"
"github.com/zserge/lorca"
"net/url"
)
var inputform string = `
<html>
<body>
<form action="/action_page.php">
<input type="text" name="username" id="username">
<input type="text" name="address" id="address">
<input type="submit" onclick="golangfunc()">
</form>
</body>
</html>
`
func main(){
ui, _ := lorca.New("data:text/html,"+url.PathEscape(inputform), "", 480, 320)
ui.Bind("golangfunc", func() {
username := ui.Eval(`document.getElementById('username').value`)
address := ui.Eval(`document.getElementById('address').value`)
fmt.Println(username, address)
})
defer ui.Close()
<-ui.Done()
}
