嗨,我想从数据表中获取选中的复选框值,在我的表中,我有两列,第一列是复选框,第二列是显示值。
这里只是返回一个复选框。我们怎么知道有点击发生? 救救我。
这是代码
function BindColumSelectTable(DataExchangeList) {
debugger
$('#columnSelectTable').DataTable({
"data": DataExchangeList,
"destroy": true,
"columns": [
{
data: 'check', render: function (data, type, row) {
debugger;
return '<input type="checkbox"/>'
}
},
{ data:"FieldCaption" },
],
"columnDefs": [
{
orderable: false,
className: "select-checkbox",
targets:0
},
{ className:"tabletdAdjust","targets":[1]}
],
});}
我正在使用jquery数据表
答案 0 :(得分:0)
function BindColumSelectTable(DataExchangeList) {
$('#columnSelectTable').DataTable({
"data": DataExchangeList,
"destroy": true,
"columns": [
{
data: 'check', render: function (data, type, row) {
var checkbox = $("<input/>",{
"type": "checkbox"
});
if(data === "1"){
checkbox.attr("checked", "checked");
checkbox.addClass("checked");
}else{
checkbox.addClass("unchecked");
}
return checkbox.prop("outerHTML")
}
},
{ data:"FieldCaption" },
],
"columnDefs": [
{
orderable: false,
className: "select-checkbox",
targets:0
},
{ className:"tabletdAdjust","targets":[1]}
],
});}

这是我使用onclick函数的答案,每次单击都会触发功能
function BindColumSelectTable(DataExchangeList) {
debugger
$('#columnSelectTable').DataTable({
"data": DataExchangeList,
"destroy": true,
"columns": [
{
data: 'ColumnCheck', render: function (data, type, row) {
debugger;
return '<input type="checkbox" onclick="ColumnCheck(this)"/>'
}
},
{ data:"FieldCaption" },
],
"columnDefs": [
{
orderable: false,
className: "select-checkbox",
targets:0
},
{ className:"tabletdAdjust","targets":[1]}
],
});
}
上面的代码与我在问题中使用的相同,只是我添加的一件事是onclick函数
和onclick函数是
function ColumnCheck(thisObj) {
debugger;
var dataExchangeCheckColumnVM = $('#columnSelectTable').DataTable().row($(thisObj).parents('tr')).data();
var dataExchangeCheckColumnList = $('#columnSelectTable').DataTable().rows().data();
for (var i = 0; i < dataExchangeCheckColumnList.length; i++) {
if (dataExchangeCheckColumnList[i].FieldCaption !== null) {
if (dataExchangeCheckColumnList[i].FieldCaption === dataExchangeCheckColumnVM.FieldCaption) {
dataExchangeCheckColumnList[i].ColumnCheck = thisObj.checked;
}
}
}
_dataExchangeColumnList = dataExchangeCheckColumnList;
}
所以我使用了** ColumnCheck **属性,它是布尔变量。如果选中复选框,则每次迭代都会添加一个真值
