Yii2 $ this-> registerJs($ js);如何在$ js内传递php变量 [英] Yii2 $this->registerJs($js); How to pass php variable inside the $js

问题描述

下面是我认为的ajax脚本.

Below is my ajax script in my view.

$js = <<< JS
    $('.list-link').click(function(){
        $.ajax({
            url: '?r=public/getlist&param1=01&param2=02&param3=03',
            dataType: "json",
            success: function(data) {
                $(".well").html(data.id);                
            }
        })
    });
JS;
$this->registerJs($js);

现在我的问题是我该如何使param1，param2和param3的值动态化，就像我要通过php变量将params1传递给3一样.

Now my problem is how am I going to make the values of param1, param2 and param3 dynamic like I am going to pass the params1 to 3 from php variables.

推荐答案

您可以这样做:

$url = \yii\helpers\Url::to([
    'public/getlist', 
    'param1' => '01', 
    'param2' => '02', 
    'param3' => '03'
]);

$js = <<< JS
    $('.list-link').click(function(){
        $.ajax({
            url: $url,
            dataType: "json",
            success: function(data) {
                $(".well").html(data.id);                
            }
        })
    });
JS;
$this->registerJs($js);

当然，您也可以使参数数量动态化，因为它只是一个传递给

Of course you can make the number of parameters dynamic as well since it is just an array that gets passed to Url::to().
