我正在使用谷歌API进行几何定位。目前,当我键入地址自动完成工作和鼠标单击时,经度和经度附加在div中。我的问题是如果我按回车键而不是鼠标点击该页面将刷新。实际上,当从自动完成中选择数据时,请刷新页面并输入。请检查下面的代码并帮助我解决问题。

输入提交表单。您需要禁用该密钥或提交事件(例如,在适当的事件处理程序(密钥事件或提交事件)中使用e.preventdefault()

提交事件最好连接到表单元素和键盘事件(或文档)。

e.g。

$('form').submit(function(e){
    e.preventDefault();
});

但你可能只需要这个:

$('form').keypress(function(e) { 
    return e.keyCode != 13;
});

你可以这样做:

var input = document.getElementById('area');
    google.maps.event.addDomListener(searchBox, 'keydown', function (e) {
        if (e.keyCode == 13) {
            e.preventDefault();
        }
    });
