解析json字符串中的var

Question

我从json字符串解析变量时遇到问题。变量（trackingID）是用于点击目标跟踪的动态网址参数，它会根据访问者来源动态更改。

var trackingID = window.location.search.substring(1);
clicky_custom.goal = { name: 'project-name - trackingID' };

Answer 1

clicky_custom.goal = { name: 'project-name - ' + trackingID };

Answer 2

这可能是您案例的合适解决方案

var trackingID = req.query.trackingID;  //Get trackingID from query string

if(typeof trackingID != 'undefined'){

      var name = {projectName: ''};

      name.projectName = 'project-name ' + trackingID;

      clicky_custom.goal = name
}
