Get column index from column name in Kendo grid in Javascript
提问by sanjeev40084
Is there a way we can find out the index of column in grid, if we know the column name in Kendo grid?
如果我们知道 Kendo 网格中的列名，有没有办法找出网格中列的索引？
e.g.
例如
EmployeeID| Name
123 | John
I want to know the index of 'Name' field i.e. 1 in the grid. Any suggestions.
我想知道“名称”字段的索引，即网格中的 1。有什么建议。
Thanks.
谢谢。

function GetColumnIndexFromName() {
var index = -1;
var strName = $("#txtColumnName").val();
var grid = $("#example").data("kendoGrid");
var columns = grid.options.columns;
if (columns.length > 0) {
for (var i = 0; i < columns.length; i++) {
if (columns[i].field == strName) { // columns[i].title -- You can also use title property here but for this you have to assign title for all columns
index = i;
}
}
}
if (index == -1) {
alert("column name not exists");
}
else {
alert("column index is:- " + index);
}
}
</script>
</body>
</html>
Let me know if any concern.
如果有任何问题，请告诉我。

This code will give the column object:
此代码将提供列对象：
var grid = $('#grid').getKendoGrid();
grid.columns.find(function(v, i) { return grid.columns[i].field == 'myColumnName'; })
Of course you can customize the filter further if you want.
当然，您可以根据需要进一步自定义过滤器。
