[英]How to get selected row values from a table
我正在将HTML表转换为数组,并将其传递给用于插入多行的控制器。 我可以创建数组,但是问题是它正在创建一个完整的表数组,但是我只想获取选定的行td
值。
//function to convert HTML table to array//
var HTMLtbl = {
getData: function (table) {
var data = [];
table.find('tr').not(':first').each(function(rowIndex, r) {
var cols = [];
// I believe the main problem is here:
$(this).find('td').each(function(colIndex, c) {
cols.push($(this).text().trim());
});
data.push(cols);
});
return data;
}
}
$(document).on('click', '#btnsave', function() {
var data = HTMLtbl.getData($('#tblresult'));
var parameters = {};
parameters.array = data;
var request = $.ajax({
async: true,
cache: false,
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
url: "../Home/Save_SearchCarsDocs",
data: JSON.stringify(parameters)
});
request.done(function(msg) {
alert("Row saved " + msg.d);
});
您可以尝试关注...
//function to convert HTML table to array//
var excludedTD_Index = [0,5,7]; // define what you want to exclude by index
var HTMLtbl = {
getData: function (table) {
var data = [];
table.find('tr').not(':first').each(function(rowIndex, r) {
var cols = [];
// I believe the main problem is here:
$(this).find('td').each(function(colIndex, c) {
if(excludedTD_Index.indexOf(colIndex) >=0) // exclude TD
continue;
cols.push($(this).text().trim());
});
data.push(cols);
});
return data;
}
}
$(document).on('click', '#btnsave', function() {
var data = HTMLtbl.getData($('#tblresult'));
var parameters = {};
parameters.array = data;
var request = $.ajax({
async: true,
cache: false,
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
url: "../Home/Save_SearchCarsDocs",
data: JSON.stringify(parameters)
});
request.done(function(msg) {
alert("Row saved " + msg.d);
});
或者,如果您可以将以下数据添加到TD标签,则可以使其更易于管理
<td data-exclude="1">
...
添加以上数据后,您可以按以下方式排除这些列
var HTMLtbl = {
getData: function (table) {
var data = [];
table.find('tr').not(':first').each(function(rowIndex, r) {
var cols = [];
// I believe the main problem is here:
$(this).find('td').each(function(colIndex, c) {
if($(this).data("exclude") == 1) // exclude TD
continue;
cols.push($(this).text().trim());
});
data.push(cols);
});
return data;
}
}
谢谢罗里·麦克罗桑(Rory McCrossan)终于得到了我的答案,我在下面添加了我的解决方案
var CB=1;
var HTMLtbl =
{
getData: function (table) {
var data = [];
table.find('tr').not(':first').each(function (rowIndex, r) {
if ($("#chk_" + CB).is(':checked'))
{
var cols = [];
$(this).find('td').each(function (colIndex, c) {
cols.push($(this).text().trim());
});
data.push(cols);
}
CB++;
});
CB = 1;
return data;
}
}
