In this article, the editor introduces in detail "how to deal with shared location data in JavaScript". The content is detailed, the steps are clear, and the details are handled properly. I hope this article "how to deal with shared location data in JavaScript" can help you solve your doubts.

There may be situations where users do not want to share their location data with you. To handle this situation, you can provide two getCurrentLocation () functions when the function is called.

If your geolocation attempt is successful, the first function is called, and if your geolocation attempt fails, the second function is called. Let's look at an example:

Try this code for example »

Handling Geolocation Errors

/ / Set up global variable

Var result

Function showPosition () {

/ / Store the element where the page displays the result

Result = document.getElementById ("result")

/ / If geolocation is available, try to get the visitor's position

If (navigator.geolocation) {

Navigator.geolocation.getCurrentPosition (successCallback, errorCallback)

Result [XSS _ clean] = "Getting the position information..."

} else {

Alert ("Sorry, your browser does not support HTML5 geolocation.")

}

}

/ / Define callback function for successful attempt

Function successCallback (position) {

Result [XSS _ clean] = "Your current position is (" + "Latitude:" + position.coords.latitude + "," + "Longitude:" + position.coords.longitude + ")"

}

/ / Define callback function for failed attempt

Function errorCallback (error) {

If (error.code = = 1) {

Result [XSS _ clean] = "You've decided not to share your position, but it's OK. We won't ask you again."

} else if (error.code = = 2) {

Result [XSS _ clean] = "The network is down or the positioning service can't be reached."

} else if (error.code = = 3) {

Result [XSS _ clean] = "The attempt timed out before it could get the location data."

} else {

Result [XSS _ clean] = "Geolocation failed due to unknown error."

}

}
