Yii2:isAjax返回false [英] Yii2: isAjax returns false
问题描述
我正在使用ajax在yii2中开发一个搜索栏.问题是Yii::$app->request->isAjax
属性始终返回false
Im developing a search bar in yii2 using ajax. The problem is the Yii::$app->request->isAjax
property always returns false
这是我的动作
public function actionAjaxsearch()
{
if(Yii::$app->request->isAjax)
{
$keywords = Yii::$app->request->queryParams;
Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
return [
'data' => $keywords,
'code' => 200
];
}
else throw new \yii\web\HttpException(404, 'Page not found.');
这是我的脚本:
$('#search-box').keyup(function( event ){
event.preventDefault();
$.ajax({
url: 'http://localhost/items/ajaxsearch',
data: {keywords: $( '#search-box' ).val()},
type: 'GET',
dataType: 'json',
}).done(function(){
console.log('success');
}).fail(function( data ){
alert( data );
}).always(function(){
alert('finished');
})
});
如果我不将if
与Yii::$app->request->isAjax
一起使用,则控制器仅使用数据呈现JSON.
If i dont use the if
with Yii::$app->request->isAjax
the controller just render the JSON with the data.
P.D #search-box
的内容已成功传递.
P.D The content of #search-box
is succesfully passed.

推荐答案
好吧,由于某些原因,您的浏览器不会将HTTP_X_REQUESTED_WITH
标头发送到服务器.
Well, your browser for some reasons does not send the HTTP_X_REQUESTED_WITH
headers to the server.
它可能与以下内容有关:跨域AJAX不会发送X-Requested-With标头
It guess it might be related to: Missing X-Requested-With: XMLHttpRequest (causes 200 OK But Shows as Error?) and Cross-Domain AJAX doesn't send X-Requested-With header
