由于某種原因，我無(wú)法讓全局變量計(jì)數(shù)器增加，即使它在發(fā)生 count++ 的函數(shù)內(nèi)增加也是如此。我的輸出結(jié)果在函數(shù)內(nèi)輸出的文本和函數(shù)外部的文本之間是不同的。知道我在這里做錯(cuò)了什么嗎？Survey.oncomplete 函數(shù)結(jié)果的每次迭代計(jì)數(shù)不應(yīng)該增加嗎？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});
