[英]How do I get the value of a text field using AngularJS?
我想在提交表單時使用AngularJS獲取文本字段值的值。
下面的代碼始終顯示“未定義”。
HTML:
<form ng-submit="AdvanceSearchSubmit($event)" name="AdvanceSearch" novalidate>
<p ng-show="!AdvanceSearch.SearchKeyWord.$pristine && AdvanceSearch.SearchKeyWord.$invalid" class="text-danger">Text Cannot Be Empty!</p>
<div ng-hide="AdvanceSearchModel" class="input-group">
<input name="SearchKeyWord" ng-model="SearchKeyWord" id="SearchKeyWord" class="form-control" placeholder="Search in timeline...." type="text" required>
<span class="input-group-btn" ng-click="isAdvanceSearch='false'; SearchPost(0,'true')">
<button ng-disabled="AdvanceSearch.$invalid" type="submit" name="search" id="search-btn" class="btn btn-flat">
<i class="fa fa-search"></i>
</button>
</span>
</div>
</form>
一種嘗試:
$scope.AdvanceSearchSubmit = function(event)
{
alert(event.target.value);
};
另一嘗試:
$scope.AdvanceSearchSubmit = function(event)
{
alert(event.SearchKeyWord.value);
};
代替event
將SearchKeyWord
作為參數傳遞
ng-submit="AdvanceSearchSubmit(SearchKeyWord)"
調節器
$scope.AdvanceSearchSubmit = function(keyWord)
{
alert(keyWord);
};
提交時,您根本不需要將事件傳遞給AdvanceSearchSubmit
。 您已經在$scope
值,例如ng-model
用於輸入字段,例如ng-model="SearchKeyWord"
alert($scope.SearchKeyWord); //access value from `$scope` directly
