javascript - 按下键时显示弹出窗口

标签 javascript jquery html css keyboard-events

我的弹出窗口在右上角有一个“关闭”按钮，一些带有背景图像的文本，底部有一个“打印”按钮。加载页面时会自动显示弹出窗口。如果有人关闭它，除非您重新加载页面，否则无法将其取回。当按下字母“G”或“g”但无济于事时，我一直试图让弹出窗口在关闭后显示出来。我找到了 this我认为可以将其实现到我现有的代码中，但我无法做到这一点。

请注意，我更愿意使用当前 JS 代码中的现有功能，而不是必须下载的插件。我的代码如下:

$(document).ready(function() {
    $(function(){
  
      $('#PopUp').css("visibility", "visible"); 
       $('#PopUp').css("opacity", 1); 
  
       });
  
  $( ".close" ).click(function() {

       $('#PopUp').css("visibility", "hidden"); 
       $('#PopUp').css("opacity", 0);
    });
});

        function printDiv()
        {
            var content = document.getElementById('printableDiv').innerHTML;
            var win = window.open();
            win.document.write(content);
            win.print();	// JavaScript Print Function
            win.close();	//It will close window after Print.
	document.getElementById("pdf1").style.top=117 + "px";  
        }

最佳答案

您可以在文档主体(或您喜欢的其他目标)上设置一个 keyup 事件来显示弹出。

$(document.body).keyup(function(e){
  var key=e.which||e.keyCode;
  if(key==71){
    $("#PopUp").css({opacity:"1",visibility:"visible"})
  };
