我是Coffeescript的新手并且在语法方面苦苦挣扎。任何人都可以帮我解决如何在CS中编写以下内容吗?
$("#getLocation").click(function() {
$('#location-loading').show();
navigator.geolocation.getCurrentPosition(applyLocation);
return false;
});
function applyLocation(location) {
$('#LogLongitude').val(location.coords.longitude);
$('#LogLatitude').val(location.coords.latitude);
alert('Latitude:' + location.coords.latitude + ', Longitude: ' + location.coords.longitude + ', Accuracy: ' + location.coords.accuracy);
$('#location-loading').hide();
}
我认为以下内容可行,但我在调用函数时返回错误(因此我没有按照链接)。
$('#getLocation').click ->
$('#location-loading').show()
navigator.geolocation.getCurrentPosition(applyLocation)
false
applyLocation = (location) ->
$('#LogLongitude').val(location.coords.longitude)
$('#LogLatitude').val(location.coords.latitude)
alert('Latitude:' + location.coords.latitude + ', Longitude: ' + location.coords.longitude + ', Accuracy: ' + location.coords.accuracy)
$('#location-loading').hide()
答案 0 :(得分:1)
你可以省略简单函数调用的()
parethesis(不链接)
并将下部的字符串放入双配额中,以便能够使用#{}
语法,
但除了你的代码确实看起来很咖啡;)
$('#getLocation').click ->
$('#location-loading').show()
navigator.geolocation.getCurrentPosition applyLocation
false
applyLocation = (location) ->
coords = location.coords
$('#LogLongitude').val coords.longitude
$('#LogLatitude').val coords.latitude
alert "Latitude: #{coords.latitude},
Longitude: #{coords.longitude},
Accuracy: #{coords.accuracy}"
$('#location-loading').hide()
