[英]Kendo Grid, dynamically adding column in $timeout, ends up in 'kendo.all.js:121639Uncaught TypeError: Cannot read property 'classList' of undefined'
Kendo Grid在$ timeout中動態添加列，最終出現在'kendo.all.js：121639Uncaught TypeError：Cannot read property'classList'of undefined'
請參考DOJO http://dojo.telerik.com/@datha_k/axITa。我在單擊按鈕按鈕時添加了一些$ timeout的列。 我不明白為什么這段代碼會在文件kendo.all.js：121639中給出錯誤“未捕獲的TypeError：無法讀取未定義的屬性'classList'”。
請幫忙！
