我正试图为我的网站做分页.(http://anuntorhei.md)

代码:

var someVar = 50;


function someStupidFunction() {
        if (objJson.length > 50) {
                document.getElementById("nextPage").style.visibility = "visible";
        }

        if (someVar <= 50) {
                document.getElementById("prevPage").style.visibility ="hidden";
        } else {
                document.getElementById("prevPage").style.visibility = "visible";
        }
}


function nextPage() {
        document.getElementById("listingTable").innerHTML = "";

        if (someVar < objJson.length) {
                document.getElementById("nextPage").style.visibility = "visible";
        } else {
                document.getElementById("nextPage").style.visibility = "hidden";
        }

        for (var i = someVar - 50; i < someVar; i++) {
                document.getElementById("listingTable").innerHTML += objJson[i].adName + "<br>";
        }

        someVar += 50;

        document.getElementById("prevPage").style.visibility = …

使用./gradlew assembleDebug构建apk后出现此错误.如果我使用./gradlew assembleRelease构建apk,我在手机上安装应用程序时出错.当我使用react-native run-android在虚拟设备中运行相同的应用程序时,应用程序正常运行,没有任何麻烦.有任何想法吗？

  "dependencies": {
    "react": "16.2.0",
    "react-native": "0.52.0",
    "react-navigation": "^1.0.0-beta.27"
  },
  "devDependencies": {
    "babel-jest": "22.1.0",
    "babel-preset-react-native": "4.0.0",
    "jest": "22.1.1",
    "react-test-renderer": "16.2.0",
    "util": "^0.10.3"
  },

我试着解决几天的问题,但无法理解一些事情.我有一个使用NodeJS和ExpressJS创建的网站,并且为了处理表单,我使用了body-parser.

    var adName = req.body.adName;
    var adMessage = req.body.adMessage;
    var phone = req.body.phone;
    var rawPrice = req.body.price;
    var rawCurrency = req.body.currency;

因此,使用此方法我处理表单值.但现在,我需要使用node-formidable来解析用户的图像.问题是,我可以以某种方式使用强大的图像和身体解析器的形式吗？或者,任何人都可以帮助我强大,了解如何处理表单并将值附加到我的变量？
