数据表按钮启用/禁用示例不工作 [英] datatables buttons enable/disable example not working
问题描述
问题是,当我取消选择该行时,该按钮仍然启用。选择/取消选择行时,启用/禁用按钮的方法是什么?
var table = $('#示例')DataTable({
serverSide:true,
dom:'Bfrtip',
ajax:'/ get?op = 2',
列:[
{data:'id'},
// more columns
],
按钮:[
{
text:'New',
action :function(e,dt,node,config){
window.location.href ='/ property?option = new'
}
},
{
文本:'Modify',
action:function(e,dt,node,config){
window.location.href ='/ property?option = modify& id ='+ data.id
},
enabled:false
},
{
text:'Delete',
action:function(e,dt,node,config){
},
enabl ed:false
}
],
select:true
});
table.on('select',function(){
var selectedRows = table.rows({selected:true}).count();
table.button(1).enable(selectedRows === 1);
table.button(2).enable(selectedRows === 1);
table.button(3).enable(selectedRows === 1);
//table.button(1).enable(selectedRows> 0);
});
另外如何获取所选行的id值?
action:function(e,dt,node,config){
window.location.href ='/ property?option = modify& id =' + data.id
},
你需要添加一个事件处理程序来取消选择。请参阅 https://datatables.net/reference/event/deselect
它应该像下面这样...
table.on('deselect',function() table.button(1).disable(); table.button(2).disable(); table.button(3).disable();});
至于获取行ID,可以找到一个示例 here
I'm using datatables with custom buttons. I'm looking in the examples, also googled a bit but I didn't find a working solution.
The problem is that, when I deselect the row the button is still enabled. What is the proper way to enable/disable the buttons when a row is selected/deselected?
var table = $('#example').DataTable( {
serverSide: true,
dom: 'Bfrtip',
ajax: '/get?op=2',
columns: [
{ data: 'id' },
// more columns
],
buttons: [
{
text: 'New',
action: function ( e, dt, node, config ) {
window.location.href = '/property?option=new'
}
},
{
text: 'Modify',
action: function ( e, dt, node, config ) {
window.location.href = '/property?option=modify&id=' + data.id
},
enabled: false
},
{
text: 'Delete',
action: function ( e, dt, node, config ) {
},
enabled: false
}
],
select: true
} );
table.on( 'select', function () {
var selectedRows = table.rows( { selected: true } ).count();
table.button( 1 ).enable( selectedRows === 1 );
table.button( 2 ).enable( selectedRows === 1 );
table.button( 3 ).enable( selectedRows === 1 );
//table.button( 1 ).enable( selectedRows > 0 );
} );
Also how can I get the id value for the selected row?
action: function ( e, dt, node, config ) {
window.location.href = '/property?option=modify&id=' + data.id
},
You need to add an event handler for the deselect. see https://datatables.net/reference/event/deselect
It should be something like below...
table.on( 'deselect', function () {
table.button( 1 ).disable();
table.button( 2 ).disable();
table.button( 3 ).disable();
} );
As for getting a row id an example can be found here
