javascript - 将keydown添加到点击事件

Question

编辑**

在我的文字游戏中有一个包含 3 个字母单词的网格。

游戏的目的是通过点击旁边相应的字母来拼写单词。

当网格中的某个区域突出显示时，它会向用户指示要拼写的单词。用户点击网格边上的字母，然后移动到突出显示的区域。

当一个字母被点击时，它会移动到网格中的相应区域。我想让它尽可能对用户友好，所以我想另外添加“keyDown()”，以便当用户按下“a”时它会在屏幕上显示动画。

字母是这样存储在 HTML 中的

<div class="tiles-wrapper">

        <div id="drag1" class="drag ui-widget-content player-tiles2" tabindex="0" data-letter="a">
        <p>a</p>

我有一些脚本，但我不知道如何链接起来

$(document).keypress(function(e){  

        if (e.which >= 97 && e.which <= 122) {  
              animateDrag(String.fromCharCode(e.which));  
    } 

});

Answer 1

您可以通过在适当的字母 div 上触发 click 事件来完成此操作，如下所示:

$(document).keypress(function(e){ 
            if (e.which >= 97 && e.which <= 122) {  
                  letter = String.fromCharCode(e.which);
                  $(".drag[data-letter='"+letter+"']").trigger('click');
            }

});
