几个月前我一直在研究这个项目,有点忘了它。无论如何,我现在要尝试完成它。我的问题是这个。我有一个动态创建的表,其中每个单元格都是可点击的。在单击时,您可以选择使用与阵列不同的图像填充表格的单元格。这可以。使用localstorage我可以在点击完成后保存表状态以反映所做的更改,但是当我退出页面并重新输入更改的图像时,会重新绘制但是表格不再可点击。我正在努力寻找解决方案。也许你可以帮忙吗?这是一些代码:
function makeChart() {
table = document.createElement('table');
var taskName = document.getElementById('taskname').value,
header = document.createElement('th'),
numDays = document.getElementById('days').value, //columns
howOften = document.getElementById('times').value, //rows
row,
r,
col,
c;
target= numDays*howOften;
var cel = null;
var myImages = new Array();
myImages[0] = "../www/images/test.png";
myImages[1] = "../www/images/test.png";
myImages[2] = "../www/images/test.png";
var my_div = document.createElement("div");
my_div.id = "showPics";
document.body.appendChild(my_div);
var newList = document.createElement("ul");
my_div.appendChild(newList);
if (taskName == '' || numDays == '') {
alert('Please enter task name and number of days');
}
if (howOften == '') {
howOften = 1;
}
if (taskName != '' && numDays != '') {
for (var i = 0; i < myImages.length; i++) {
var allImages = new Image();
allImages.src = myImages[i];
allImages.onclick = function (e) {
if (sel !== null) {
sel.src = e.target.src;
my_div.style.display = 'none';
sel.onclick = null;
sel = null;
}
};
var li = document.createElement('li');
li.appendChild(allImages);
newList.appendChild(li);
}
my_div.style.display = 'none';
header.innerHTML = taskName;
table.appendChild(header);
function addImage(col) {
var img = new Image();
img.src = "../www/images/imageholder.png";
col.appendChild(img);
img.onclick = function () {
my_div.style.display = 'block';
sel = img;
};
}
for (r = 0; r < howOften; r++) {
row = table.insertRow(-1);
for (c = 0; c < numDays; c++) {
col = row.insertCell(-1);
addImage(col);
}
}
document.getElementById('singleUser').appendChild(table);
var blankVal = {
value : ''
};
$("#taskname").attr(blankVal);
$("#days").attr(blankVal);
$("#times").attr(blankVal);
document.getElementById('createChart').onclick = null;
saveData();
}
}
function saveData(){
localStorage.setItem(name, table.innerHTML);
}
function showData(){
var showme = localStorage.getItem(name);
var newTable = document.createElement('table');
newTable.innerHTML= showme;
newTable.id = "newTable";
var showIt= document.getElementById('holdTable');
showIt.appendChild(newTable);
console.log(showIt);
};
