我当前正在使用:
function searchNotes() {
const url = "http://localhost:2609/api/notes"
$.ajax({
url: url,
type: 'GET',
success: function (notesList) {
console.log(notesList)
// EXTRACT VALUE FOR HTML HEADER.
var col = [];
for (var i = 0; i < notesList.length; i++) {
for (var key in notesList[i]) {
if (col.indexOf(key) === -1 && (key === 'title' || key === 'content' || key == 'category' || key == 'categoryId')) {
col.push(key);
}
}
}
// CREATE DYNAMIC TABLE.
var table = document.createElement("table");
// CREATE HTML TABLE HEADER ROW USING THE EXTRACTED HEADERS ABOVE.
var tr = table.insertRow(-1); // TABLE ROW.
for (var i = 0; i < col.length; i++) {
var th = document.createElement("th"); // TABLE HEADER.
th.innerHTML = col[i];
tr.appendChild(th);
}
// ADD JSON DATA TO THE TABLE AS ROWS.
for (var i = 0; i < notesList.length; i++) {
tr = table.insertRow(-1);
for (var j = 0; j < col.length; j++) {
var tabCell = tr.insertCell(-1);
tabCell.innerHTML = notesList[i][col[j]];
}
}
// FINALLY ADD THE NEWLY CREATED TABLE WITH JSON DATA TO A CONTAINER.
var divContainer = document.getElementById("listNotes");
divContainer.innerHTML = "";
divContainer.appendChild(table);
}
});
}
使用jquery创建html表。该表如下所示:
我想按在顶部下拉菜单中选择的categoryId过滤表,然后我要删除categoryId列。有什么想法可以实现吗?
答案 0 :(得分:1)
您需要在notesList对象上使用.sort(),如下所示:
notesList.sort(function(a, b) {
return a.categoryId - b.categoryId;
});
在将值附加到html之前将其放置。
要“删除” categoryId列非常简单:只需从if语句中删除以下位:
|| key == 'categoryId'
所以您的最终结果是这样的:
function searchNotes() {
const url = "http://localhost:2609/api/notes"
$.ajax({
url: url,
type: 'GET',
success: function (notesList) {
notesList.sort(function(a, b) {
return a.categoryId - b.categoryId;
});
// EXTRACT VALUE FOR HTML HEADER.
var col = [];
for (var i = 0; i < notesList.length; i++) {
for (var key in notesList[i]) {
if (col.indexOf(key) === -1 && (key === 'title' || key === 'content' || key == 'category')) {
col.push(key);
}
}
}
// CREATE DYNAMIC TABLE.
var table = document.createElement("table");
// CREATE HTML TABLE HEADER ROW USING THE EXTRACTED HEADERS ABOVE.
var tr = table.insertRow(-1); // TABLE ROW.
for (var i = 0; i < col.length; i++) {
var th = document.createElement("th"); // TABLE HEADER.
th.innerHTML = col[i];
tr.appendChild(th);
}
// ADD JSON DATA TO THE TABLE AS ROWS.
for (var i = 0; i < notesList.length; i++) {
tr = table.insertRow(-1);
for (var j = 0; j < col.length; j++) {
var tabCell = tr.insertCell(-1);
tabCell.innerHTML = notesList[i][col[j]];
}
}
// FINALLY ADD THE NEWLY CREATED TABLE WITH JSON DATA TO A CONTAINER.
var divContainer = document.getElementById("listNotes");
divContainer.innerHTML = "";
divContainer.appendChild(table);
}
});
}
