Cordova javascript error: has no method startsWith Android

Question

我有两台设备，一台是 Lollipop，一台是 Kitekat...一台 Lollipop 没有报告任何错误，但是当我尝试我的应用程序时，我收到了这个错误：

10-13 16:56:56.126: I/chromium(6322): [INFO:CONSOLE(99)] "Uncaught
TypeError: Object ALIM. IL SOLE DI LOPARDO MARIANGELA has no 
method 'startsWith'", source: file:///android_asset/www/soggetti3.html (99)

这是我的一部分 javascript:

 function onDeviceReady() {

        window.rancolor=ranColor();

        var ricerca=localStorage.getItem('testo_ricerca');
        var risultati = JSON.parse(localStorage["risultati"]);

        var ricerca1=ricerca.toString();
        ricerca1=ricerca1.toUpperCase();
        var res_match=[];

        var lll=risultati.length;

        for(var r=0;r<lll;r++){

            var ppp0=risultati[r][1].toString();
            var ppp1=risultati[r][0].toString();
            var ppp2=risultati[r][2].toString();
            var ppp3=risultati[r][3].toString();

            ppp0=ppp0.toUpperCase();
            alert(ppp0);
            alert(ricerca1);
            var check=ppp0.startsWith(ricerca1);

            if(check==true){
                res_match=res_match.concat([[ppp1,ppp0,ppp2,ppp3]]);
            }

        }
        var y=res_match.length;

我应该如何搜索字符串数组来搜索以其他字符串开头的字符串？

Answer 1

startWith函数最简单的实现方式如下所示，您可以在自己的代码中使用startsWith：

if (typeof String.prototype.startsWith != 'function') {
  // see below for better implementation!
  String.prototype.startsWith = function (str){
    return this.indexOf(str) === 0;
  };
}
