所以我使用谷歌地图api填写后端的一些信息,但如果用户没有“点击”下拉选项,后端永远不会填充数据。
我在这里找到了有关堆栈溢出的解决方法:link但是没有任何内容会在模糊/焦点上触发。
class BFrame
{
string Value{get; set;}
}
class Tag
{
BFrame Frame{get;}
}
public void func(Tag tag, string newValue)
{
PropertyInfo frameProperty = tag.GetType().GetProperty("Frame");
var oldValue = frameProperty.GetValue(tag);
//frameProperty.SetValue(tag, newValue); //Doesn't work. Throws exception because there is no setter
//TODO: Set the Value property inside the BFrame class
//Somethig like this: tag.Frame.Value = newValue;
}
我理解代码在做什么。单击选项卡或输入时,它会模拟向下箭头按下。我尝试添加一个模糊的监听器,但没有任何作用。该事件仍然被触发,但它没有选择或更新。
在这种情况下会喜欢一些帮助。谢谢!

您是否检查过输入字段是否绑定了多个下拉列表? 其他实例
var autocomplete = new google.maps.places.Autocomplete(input);
别的地方?结果我们有三个。取出其中两个后,您的解决方案对我有用。

inputAddress
作为自动填充输入,您可以执行以下操作:
// Trigger search on blur
document.getElementById('inputAddress').onblur = function () {
google.maps.event.trigger(this, 'focus', {});
google.maps.event.trigger(this, 'keydown', {
keyCode: 13
});
};
或使用Google地图事件监听器:
// Trigger search on blur
google.maps.event.addDomListener(document.getElementById("inputAddress"), 'blur', function() {
google.maps.event.trigger(this, 'focus', {});
google.maps.event.trigger(this, 'keydown', {
keyCode: 13
});
});
仅此一项就会干扰用户通过鼠标点击选择建议。因此,为了防止这种情况,您需要再进行一些检查。以下是一个完整的例子。阅读代码注释以获取更多信息。
如果您在项目中使用jQuery,请查看完全相同的this answer。
function initialize() {
var ac = new google.maps.places.Autocomplete(
(document.getElementById('inputAddress')), {
types: ['geocode']
});
ac.addListener('place_changed', function() {
var place = ac.getPlace();
if (!place.geometry) {
// User entered the name of a Place that was not suggested and
// pressed the Enter key, or the Place Details request failed.
console.log("No details available for input: '" + place.name + "'");
return;
}
console.log("You selected: '" + place.formatted_address + "'");
});
// Trigger search on blur
google.maps.event.addDomListener(document.getElementById("inputAddress"), 'blur', function() {
// Find the pac-container element
var pacContainer = nextByClass(this, 'pac-container');
// Check if we are hovering on one of the pac-items
// :hover propagates to parent element so we only need to check it on the pac-container
// We trigger the focus and keydown only if :hover is false otherwise it will interfere with a place selection via mouse click
if (pacContainer.matches(':hover') === false) {
google.maps.event.trigger(this, 'focus', {});
google.maps.event.trigger(this, 'keydown', {
keyCode: 13
});
}
});
}
function hasClass(elem, cls) {
var str = " " + elem.className + " ";
var testCls = " " + cls + " ";
return (str.indexOf(testCls) != -1);
}
function nextByClass(node, cls) {
while (node = node.nextSibling) {
if (hasClass(node, cls)) {
return node;
}
}
return null;
}
