Question

我将我的离子应用程序的输入值打印成表格格式，我注意到有一个文本＆＃34; NaN＆＃34;出现在桌子上。代码中有什么东西会导致这种情况吗？我该如何删除它？

这是我的controller.js代码：

$scope.goPrint = function()
{
    cordova.plugins.printer.print('<html><head><link rel="stylesheet" type="text/css" href="lib/ionic/css/style.css" /></head><body>' + 
    '<div><img src="img/kYYXJ9o0Qk6yNSgx8ZLb_imgpsh_fullsize.jpg" style="display: block; width: 100%; height: auto; margin-left: auto; margin-right: auto;"></div>' + 
    '<div align="left"><div class="spacer" style="height: 10px;"></div><h3 align="center">Membership Form</h3><div class="spacer" style="height: 10px;"></div>' +
    '<table class="table-border" style="width: 100%"><tr class="table-border"><td class="table-border">' + 
    'MMID: </td><td class="table-border">' + $scope.mmid + '</td></tr><tr class="table-border"><td class="table-border">' +

}

Answer 1

NaN，表示不是数字。因此，请检查您获得NaN的变量的计算。获得NaN值的原因之一可以是x / 0（不允许除以0）。或者对字符串变量进行数学运算。如果您可以显示您收到此错误的确切位置，那么我们可以提供更多帮助。
