关于这个 javascript 代码有什么问题有什么想法吗？
我有下面的代码。该代码的目的是获取本地存储中存储的所有值，并将它们显示在两个 id 为 'title' 和 'textLoc 的 HTML 元素中'。 'title' 是 ， 'textLoc' 是
var tests = [];
var titles = [];
var finalTests = "";
var key, value;
for (var i = 0; i < localStorage.length; i++) {
key = localStorage.key(i);
value = localStorage.getItem(key);
tests.push(value);
titles.push(key);
finalTests += "<tr><td><a class=\"dashlinks\" href=\"javascript:void\" onclick=\"rememberTest("+i+")\">" + key + "</a></td></tr>";
}
for (i=0; i<tests.length; i++) {
document.getElementById('title').innerHTML = titles[i];
document.getElementById('textLoc').innerHTML = tests[i];
}
I have the code below. The purpose of the code is to grab all the values stored in the local storage and display them in two HTML elements with ids of 'title' and 'textLoc'. 'title' is an <input type="text"> and 'textLoc' is a <textarea>. I want the values to be stored in the <textarea> and the keys to be stored in the <input type="text">. The values are being stored correctly but the keys are not. Any ideas on why this would be?
var tests = [];
var titles = [];
var finalTests = "";
var key, value;
for (var i = 0; i < localStorage.length; i++) {
key = localStorage.key(i);
value = localStorage.getItem(key);
tests.push(value);
titles.push(key);
finalTests += "<tr><td><a class=\"dashlinks\" href=\"javascript:void\" onclick=\"rememberTest("+i+")\">" + key + "</a></td></tr>";
}
for (i=0; i<tests.length; i++) {
document.getElementById('title').innerHTML = titles[i];
document.getElementById('textLoc').innerHTML = tests[i];
}

您应该使用
document.getElementById('title').value和document.getElementById('textLoc').value。另外，在存储 FinalTests 后，您似乎没有对它进行任何操作。You should use
document.getElementById('title').valueanddocument.getElementById('textLoc').value. Also it seems like you are doing nothing with finalTests after you store it.您应该将字符串附加到文本区域：
You should be appending the string to the text area:
