javascript - 使用 intro.js 在步骤中触发函数

Question

我已经尝试了这里的步骤: Step with click functionality in intro.js

获取在步骤中触发的函数。我没有成功执行函数，但教程仍在运行。最终目标是让函数触发按钮点击。谢谢你的帮助。

<script type="text/javascript">
  function startIntro(){
    var intro = introJs();
      intro.setOptions({
        steps: [
          {
            intro: "Welcome to the page!",
            onchange: function(){
                console.log("test");
            },
            onbeforechange: function() {
                console.log("before");
            }
          },
          {
            element: '#step1',
            intro: "You can start doing something by clicking the New Item button."
          },
          {
            element: '.thefilter',
            intro: "You can filter any of the stock items in the table by using the search fields ",
            position: 'bottom'
          }
        ]
      });
      intro.start();
  }
</script>

<a href="javascript:void(0);" onclick="startIntro();"><img style="position:fixed;" src="help.png" /></a>

我错过了示例中的某些内容，这些内容为我提供了所需的指导。

这是更新后的代码。

TLDR；删除了步骤中的内联 onchange 并将其附加到 intro.start 之前。有效!

<script type="text/javascript">
  function startIntro(){
    var intro = introJs();
      intro.setOptions({
        steps: [
          {
            intro: "Welcome to the page!"
          },
          {
            element: '#step1',
            intro: "You can start doing something by clicking the New Item button."
          },
          {
            element: '.thefilter',
            intro: "You can filter any of the stock items in the table by using the search fields ",
            position: 'bottom'
          }
        ]
      });
       intro.onbeforechange(function () {
      if (this._currentStep === 2) {
        console.log('what is happening')
        return false;
      }
    });
      intro.start();
  }
</script>

<a href="javascript:void(0);" onclick="startIntro();"><img style="position:fixed;" src="help.png" /></a>
