我有一个表格，用户可以在该表格中单击该行，然后编辑该行。我现在想将它保存回数据库。我怎样才能做到这一点？我只是不确定如何创建ajax调用来运行它。
// overlay functions
function openOverlay(){
document.getElementById("pageOverlay").style.visibility = "visible";
}
function closeOverlay(){
document.getElementById("pageOverlay").style.visibility = "hidden";
}
// show row data to be edited or view single row
$(".rowEditData").click(function() {
html = "<div id='editableTableDiv'><label class='editRowLabel'>Shape Name:</label> <input type='text' class='mdl-textfield__input' name='shapeName' value="+ $(this).find('td').eq(0).html() + "><br><label class='editRowLabel'>Number Edges:</label> <input type='text' class='mdl-textfield__input' name='numberEdges' value="+ $(this).find('td').eq(1).html() + "><br><label class='editRowLabel'>Sum of Interior Angles:</label> <input type='text' class='mdl-textfield__input' name='sumAngles' value="+ $(this).find('td').eq(2).html() + "><br><br><input type='button' class='mdl-button mdl-js-button mdl-button--raised mdl-button--colored' value='Save' onclick='saveNewRowData()'> <input type='button' class='mdl-button mdl-js-button mdl-button--raised mdl-button--colored' value='Close' onclick='closeOverlay()'></div>";
$("#pageOverlay").html(html).show();
openOverlay();
});
function saveNewRowData(){
shapeName = $("input[name=shapeName]").val();
numberEdges = $("input[name=numberEdges]").val();
sumAngles = $("input[name=sumAngles]").val();
$.ajax({
url: "someURLhere.php",
data: data,
type: "post"
});
}#pageOverlay {
display: none;
position: absolute;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, 0.25);

#pageOverlay div {

你需要ajax每一行
（文档）$。就绪（（）的函数
{$('#btn').click(function(e) {
e.preventDefault();
$('#yourTable tr').each(function(i, tr) {
var postData = {
CoumnName : $('.row-class').val(),
ColumnName : $('.row-class').val()
}
console.log(postData);
$.ajax({
type: "post",
url: "/your url",
data: postData
})
.done(function(response) {
console.log(response);
alert("Success!");
})
.fail(function(x, status, error) {
alert("Error: " + error);
});
});
});
}）;

以下是我提出的有效方法。我只是使用PHP脚本然后将数据保存到数据库。
