我收到以下错误
无法调用null
的方法'transaction'尝试插入WEBSQL时（是的，我知道它已被弃用）。
我有一个几乎完全相同的这个脚本在另一个页面上正常工作，这个只有一个不同的名称和单独的字段。代码如下。
var html5rocks = {};
html5rocks.webdb = {};
html5rocks.webdb.db = null;
html5rocks.webdb.open = function() {
var dbSize = 5 * 1024 * 1024; // 5MB
html5rocks.webdb.db = openDatabase('Customer', '1.0', 'customer manager', dbSize);
}
html5rocks.webdb.onError = function(tx, e) {
alert('Something unexpected happened: ' + e.message );
console.log('error');
}
html5rocks.webdb.onSuccess = function(tx, r) {
var statusOutput = "Customer Form Saved!";
var status = document.getElementById('status');
$('.form-title-area').css('background-color','#26c622');
$('.form-title-area').html('<h1>Customer Form Saved!</h1>');
status.innerHTML = statusOutput;
html5rocks.webdb.getAllTodoItems(loadTodoItems);
}

有没有人知道这个问题究竟是什么？我很难过
