显示列表,但在第一次按键时,结果列表并没有显示出来
这是我的密码:
<input type="text" placeholder="Search people here..." ng-change="getMatchedUser();" ng-model="selected" data-typeahead="user as user.name for user in searchMembers | filter:$viewValue" typeahead-on-select="onSelect($item, $model, $label)" typeahead-template-url="customTemplate.html" />
<script type="text/ng-template" id="customTemplate.html">
<a style="cursor: pointer;">
<div class="search-div">
<span style="float: left;"><img ng-src="<?php echo base_url().UPLOAD_PROFILE ?>{{match.model.imageUrl}}" width="30" class="img-circle"></span>
<div class="search-name">
<span>{{match.model.name}}</span><br/>
<span ng-if="match.model.skillName.length">
<i class="skill">{{match.model.skillName}}</i>
</span>
</div>
</div>
<div style="padding-bottom:42px;" ng-if="match.model.length == 5">
<a href="<?php echo base_url(); ?>#/searchResult" style="float: left; padding: 18px 1px 5px 8px; color: black;">

$scope.getMatchedUser = function(){
$scope.searchValue = $scope.selected;
$http({
method : "POST",
url : BASE_URL + 'getMatchedUser',
data : $.param({"typeValue": $scope.selected}),
headers : { 'Content-Type' : 'application/x-www-form-urlencoded'}
}).success(function(data){
if(data.status == "success"){
$scope.searchMembers = data.searchMembers;
}
});
};
$scope.getMatchedUser=函数(){
$scope.searchValue=$scope.selected;
$http({
方法:“张贴”,
url:BASE_url+'getMatchedUser',
数据:$.param({“typeValue”:$scope.selected}),
标题:{'Content Type':'application/x-www-form-urlencoded'}
}).success(函数(数据){
如果(data.status==“成功”){
$scope.searchMembers=data.searchMembers;
}
});
};
ng更改
实际上是在更新ng型号
之前触发的
我找到的一个解决方案是简单地将typeahead wait ms
属性(时间范围可以忽略不计)添加到typeaheadinput
元素中
<input type="text"
placeholder="Search people here..."
ng-change="getMatchedUser();"
ng-model="selected"
data-typeahead="user as user.name for user in searchMembers | filter:$viewValue"
typeahead-wait-ms=10
typeahead-on-select="onSelect($item, $model, $label)"
typeahead-template-url="customTemplate.html" />
这10毫秒的暂停应该足以让
ng模型在触发ng change
事件之前更新。是否typeahead on select=“onSelect($item,$model,$label)”
基本上为我们提供了模型实际更改时的挂钩?
