我这样做是根据服务器返回的数据创建的列数。我想检查数组中的数据是否与列名匹配,如果匹配则返回yes,否则返回no。
function initTable(userJvmsArray) {
var collumnsCallbacks = [{
title: "Username",
data: "username"
}];
for (var i = 0; i < $scope.unique.length; i++) {
$('#nameColumn').after('<th>' + $scope.unique[i] + '</th>');
var jvm = $scope.unique[i];
var col = {
title: jvm,
data: function(data, type, row) {
var data2 = data;
var jvms = $scope.unique;
for (var k = 1; k < jvms.length; k++) {
console.log(jvms);
for (var j = 0; j < data2.myarray.length; j++) {
if (table.column(k).title() == data2.myarray[j].Name) {
console.log(table.column(k).title() + " = " + data2.myarray[j].Name + " YES");
return "yes";
} else {
console.log(table.column(k).title() + " = " + data2.myarray[j].Name + " NO");
return "no";
}
}
}
}
};
collumnsCallbacks.push(col);
$scope.columns = collumnsCallbacks;
}
$scope.myTable = $('#myTable').DataTable({
'paging': true,
"pageLength": 3,
'columns': collumnsCallbacks
});
问题是该函数似乎多次运行并错误地填充了表,这是我的控制台日志:
["myword", "secondword", fastLoop: function, fastLoopAsc: function] myctrl.controller.js:63
user1: myword = myword YES myctrl.controller.js:66

最佳答案
原因
由于DataTables的工作方式,columns.data
的函数被多次执行。尽管尚不清楚,但是可能会多次调用此函数,因为DataTables会针对所需的不同数据类型调用它-类型检测,排序,过滤和显示(type == 'type'
,type == 'sort'
,type == 'filter'
和)。也可以调用它来设置单元格的数据(type == 'display'
)。
功能应定义如下,有关更多详细信息,请参见set == 'set'
。
data: function(row, type, set, meta){ }
笔记
您可以使用
columns.data
,它可以被视为columns.render
的只读伴侣,并且不太复杂。您在两个循环中的逻辑上有一个缺陷,它们只会运行一次,因为您会立即在内循环中返回
columns.data
或"yes"
值。我无法更正您的代码,因为不清楚您要做什么。关于javascript - DataTables rows.add(array).draw()被多次调用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/32822552/
