jQuery datepicker问题：未捕获的TypeError [英] jQuery datepicker issue: Uncaught TypeError

问题描述

我有一个jqgrid，我必须在单元格中提供标签导航。我遇到了一个奇怪的错误，到目前为止我无法理解。



我在网格中有多个日期单元，选中后，应该显示一个jquery默认的datepicker。我也碰巧将自己的textboxstyle类应用于所选的单元格。



这是我用来检测标签导航的代码：

I have a jqgrid, in which I have to provide tab navigation in the cells. I have encountered a strange error which I have failed to comprehend so far.

I have multiple date cells in the grid, which selected, should display a jquery default datepicker. I also happen to apply my own textboxstyle class to the cell which is selected.

This is the code that I am using to detect tab navigation:

afterEditCell: function (id, name, val, iRow, iCol) {
    var e = window.event;
    var charCode = e.which || e.keyCode;
    if (charCode == 9) {
        e.preventDefault();
        var $row = $grid.find('.jqgrow#' + id);
        var $columns = $row.find('td');
        $td = $($columns[iCol]);

        if (isAnyDate(iCol)) {
           $td.find('input').addClass('textBoxStyle').datepicker();  //if it is a date field then apply a datepicker
        }
        else {
            $td.find('input').addClass('textBoxStyle');
        }
   }

问题：我不断收到的错误是：

Problem: The error that I keep on getting is:

<pre lang="Javascript">Uncaught TypeError: Cannot read property 'dpDiv' of undefined jquery-ui-1.8.19.custom.min.js:65
$.extend._doKeyDown jquery-ui-1.8.19.custom.min.js:65
f.event.dispatch jquery-1.7.1.min.js:4
f.event.add.h.handle.i

奇怪的部分：当我使用鼠标浏览细胞时，并重复相同的程序，它就像一个魅力...那时没有错误..帮助？

The strange part: When I navigate through cells using mouse, and repeat the same procedure, it works like a charm...no error at that time..help?

推荐答案

row =

grid.find（' .jqgrow＃' + id）;
var

grid.find('.jqgrow#' + id); var

columns =

columns =
