Question

我已经看了好几天了，完全被卡住了。我正在处理的页面如下所示：

@GetMapping("/hello")
public void hello(@RequestParam int id){

    Span span = tracer.buildSpan("Count" + id).withTag("Number",id).start();
    try(Scope scope = tracer.activateSpan(span)){
        System.out.println("Printing 1st thing");
        hello2("Hello1");

    }finally {
        span.finish();
    }

}

private void hello2(String s){

    Span span = tracer.buildSpan("2nd Method").withTag("Name",s).start();

    try(Scope scope = tracer.activateSpan(span)){

        System.out.println("Printing 2nd Hello");

    }finally {
        span.finish();
    }
}

我设置的自定义变量如下所示：

<div class="field--item">
<span class="file file--mime-application-pdf file--application-pdf icon-before">
<div class="file-info text-center--mobile"><span class="file-icon"><span class="icon glyphicon glyphicon-file text-primary" aria-hidden="true"></span></span><div class="file-wrapper"><span class="file-name">17840.pdf</span><span class="file-size">94.35 KB</span></div></div>
<span class="file-link"><a href="/dashboard/download/17840/122526" class="resource-button" resource-name="Kennedy's actions in Vietnam in 1962" resource-file-id="122526" resource-file-type="PDF" resource-subject="History" resource-category="">Download</a>
</span></span></div>

我真正想做的是设置一个变量，当单击“下载”按钮时，该变量会引入资源名称。我知道要单独设置实际的点击跟踪等，但我无法让此函数将任何内容传递给“已定义”以外的变量。

对正确方向的任何帮助或点头都将非常感谢。谢谢！

Answer 1

也许你可以使用点击事件：

Answer 2

尝试删除最后的 text() 函数：

function getAttribute() {
  return document.getElementsByClassName('resource-button')[0].getAttribute('resource-name');
}

console.log(getAttribute());

<div class="field--item">
<span class="file file--mime-application-pdf file--application-pdf icon-before">
<div class="file-info text-center--mobile"><span class="file-icon"><span class="icon glyphicon glyphicon-file text-primary" aria-hidden="true"></span></span><div class="file-wrapper"><span class="file-name">17840.pdf</span><span class="file-size">94.35 KB</span></div></div>
<span class="file-link"><a href="/dashboard/download/17840/122526" class="resource-button" resource-name="Kennedy's actions in Vietnam in 1962" resource-file-id="122526" resource-file-type="PDF" resource-subject="History" resource-category="">Download</a>
</span></span></div>

GTM 自定义 Javascript 变量不起作用（返回函数）
