好吧,所以我有文本框输入成绩,然后将它们保存在localstorage中,我可以在我的文本框下看到它们。但是,如果我想添加更多文本框,我可以在其中添加更多成绩,并且它们将保存在localstorage中,但它们将在另一个数组中,或者我将如何做到这一点?我将不胜感激任何帮助。
$(document).ready(function () {
var i = 0;
for (i = 0; i < localStorage.length; i++) {
var gradeID = "grade-" + i;
$('#gradeList').append("<b id='" + gradeID + "'>" + localStorage.getItem(gradeID) + "</b>, ");
}
$('#clear').click(function () {
localStorage.clear();
});
$('#gradeEntryForm').submit(function () {
if ($('#gradeInput').val() !== "") {
var gradeID = "grade-" + i;
var gradeMessage = $('#gradeInput').val();
localStorage.setItem(gradeID, gradeMessage);
$('#gradeList').append("<b class='task' id='" + gradeID + "'>" + gradeMessage + "</b>, ");
var grade = $('#' + gradeID);
task.slideDown();
$('#gradeInput').val("");
i++;
}
return false;
});
$('#gradeList').on("click", "b", function (event) {
self = $(this);
gradeID = self.attr('id');
localStorage.removeItem(gradeID);
self.remove();
});
});

您可以将动态ID设置为LocalStorage键,您可以将其与生成的TextBox相关联
如下所示
localStorage['grade_' + some_id] = value;

您可以使用以下示例:
document.getElementById("addGrade").onclick = function() {
var gradeCell = document.getElementById("gradeCell");
var input = document.createElement("input");
input.type = "number";
var br = document.createElement("br");
gradeCell.appendChild(input);
gradeCell.appendChild(br);
}
