Javascript在两个地方创建元素

Question

How would I need to write this to have the elements created in two places?

Here is my code.

I have tried using document.getElementsByName and document.getElementsByClassName and neither of them work.

HTML

<p style="display:block;" class="coords"></p>

Javascript

function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition);
    } else {
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}

function showPosition(position, coords)
{
    var places = document.getElementsByClassName(coords);
    for (var i = 0; i < places.length; i++)
    {
        places[i].innerHTML = "<input type='text' name='lat' id='lat' value='" + position.coords.latitude + "'>" +
            "<input type='text' name='lon' id='lon' value='" + position.coords.longitude + "'>";
    }
}

Answer 1

After calling getElementsByClassName you must use a loop to update each of them.

function showPosition(position) {
    var places = document.getElementsByClassName("coords");
    for (var i = 0; i < places.length; i++) {
        places[i].innerHTML="<input type='text' name='lat' id='lat' value='" + position.coords.latitude + "'>" +
                            "<input type='text' name='lon' id='lon' value='" + position.coords.longitude + "'>";
    }
}

You may want to use

document.getElementsByClassName or document.getElementsByName

with no capital letter at the start
