问题
I have a basic table and I would like to search only one column.
The code I have so far is here in this fiddle.
As you can see at the bottom of each column there is a search filter, however I would only like there to be one search filter, on the office column.
It would also be good if the search filter was at the top, and not at the bottom as it is now.
Basically I'd like my table to look similar to this one, however instead of a filter on each column, I only want one filter on one column.
Any help is appreciated.
My code is below.
// Setup - add a text input to each footer cell
$('#example tfoot th').each(function() {
var title = $(this).text();
$(this).html('<input type="text" placeholder="Search ' + title + '" />');
});
// DataTable
var table = $('#example').DataTable();
// Apply the search
table.columns().every(function() {
var that = this;
$('input', this.footer()).on('keyup change', function() {
if (that.search() !== this.value) {
that
.search(this.value)
.draw();
}
});

</table>回答1:
just replace your code
$('#example tfoot th').each(function() {
var title = $(this).text();
$(this).html('<input type="text" placeholder="Search ' + title + '" />');
});
with
$('#example thead th').each(function() {
var title = $(this).text();
if(title == 'Office'){
$(this).append('<br /><input type="text" placeholder="Search ' + title + '" />');
}
});
as you can see I replaced tfoot to thead to set the search box on top. and I placed the condition to display the search box for "office"

I know this question has already been answered,
Nevertheless, it might be of use to some people...
Alternative Minimized Example :
From :
// Setup - add a text input to each footer cell
$('#example tfoot th').each(function() {
var title = $(this).text();
$(this).html('<input type="text" placeholder="Search ' + title + '" />');
});
// DataTable
var table = $('#example').DataTable();
// Apply the search
table.columns().every(function() {
var that = this;
$('input', this.footer()).on('keyup change', function() {
if (that.search() !== this.value) {
that
.search(this.value)
.draw();
}
});
To :
//Setup - add a text input to each footer cell
$('#example tfoot th').each(function(i) {
var title = $(this).text();
var events = 'onchange="SearchCol(this,'+i+')"'
events+= ' onkeyup="SearchCol(this,'+i+')"'
$(this).html('<input type="text" '+events+' placeholder="Search '+title+'" />');
});
// Search Specific Column
function SearchCol(input,col_index){
var query = $(input).val()
$("#example").DataTable().column(col_index).search(query).draw()
}
