全局计数变量不增加

Question

由于某种原因，我无法让全局变量计数器增加，即使它在发生 count++ 的函数内增加也是如此。我的输出结果在函数内输出的文本和函数外部的文本之间是不同的。知道我在这里做错了什么吗？Survey.oncomplete 函数结果的每次迭代计数不应该增加吗？Survey    .StylesManager    .applyTheme("modern");var kn2 = "LwrHXqFRN_pszCopTKHF_Q"var kn3 = "exroCUoYl4wVzs7pKU_49w"var count = 0var keyname = ("kn" + count)var mapilink = "https://images.mapillary.com/" + (keyname) + "/thumb-1024.jpg";var json = { pages: [  {   name: "page1",   elements: [    {     type: "image",     name: "image",     imageLink: (mapilink),     imageHeight: 580,     imageWidth: 640    },    {     type: "html",     name: (keyname),     visible: false,     html: (keyname)    },    {     type: "rating",     name: "Walkability",     title: "How walkable does this look to you"    },    {     type: "rating",     name: "Saftey",     title: "How safe does this look to you"    },    {     type: "rating",     name: "Comfortability",     title: "How comfortable does this look to you"    }   ]  } ]}window.survey = new Survey.Model(json);var username = document.getElementById("user").value;survey    .onComplete    .add(function (result) {        count ++;        var PID = document.getElementById("user").value;        var results = PID + "_" + (keyname) + ":\n" + JSON.stringify(result.data, null, 3) + (count) ;        document            .querySelector('#surveyResult')            .textContent = results;    survey.clear();    survey.render();    });$("#surveyElement").Survey({model: survey});

Answer 1

 基本上，需要将所有内容包装在更多函数中。

函数输出函数文本而不是预期输出
