Question

请帮助我！！问题是该值未出现在输入框中。我正在使用数组将拆分的QR码文本存储到单独的输入框中以存储到数据库中。这使用cordova条码扫描器插件。

var resultDiv;
var testdiv;
var testdiv2;

document.addEventListener("deviceready", init, false);

function init() {
    document.querySelector("#startScan").
        addEventListener("touchend", startScan, false);
	
	testdiv = document.querySelector("#txtFname");

	testdiv2 = document.querySelector("#txtFname");
	
	resultDiv = document.querySelector("#text4");
	
}

function startScan() {

	cordova.plugins.barcodeScanner.scan(
        
        function (result) {
			
			var result ;
			arr = result.text.split('|'),
			i;
			
			for(i in arr){
				result.format;
				result.cancelled;
				testdiv.value = arr[0];//
				testdiv2.value = arr[1];
				resultDiv.value = arr[2];
			}

		/*	var s = result.text.split('|');
            result.format;
			result.cancelled;
			resultDiv.value = s;*/
		
		},
        

		function (error) {
			alert("Scanning failed: " + error);
		}
	);
	

}

这是困扰我开发应用程序的问题。看起来您的帖子大部分是代码；请添加更多详细信息。
