如何修复在free-jqgrid中无法读取未定义的属性“rowIndexes”

Question

如果通过单击内联编辑或工具栏内联编辑按钮启动内联编辑，则javascript异常。

Column 15TypeError: Cannot read property 'rowIndexes' of undefined  

在http://localhost:52216/admin/Scripts/jqgrid-4.9.1/js/jquery.jqgrid.src.js:5135:15

Function.jQuery.extend.each (http://localhost:52216/admin/Scripts/jquery-1.11.2.js:384:23) at jQuery.fn.jQuery.each (http://localhost:52216/admin/Scripts/jquery-1.11.2.js:136:17)

在jgrid.extend.getGridRowById (http://localhost:52216/admin/Scripts/jqgrid-4.9.1/js/jquery.jqgrid.src.js:5133:9)

在http://localhost:52216/admin/Scripts/jqgrid-4.9.1/js/jquery.jqgrid.src.js:5498:31

Function.jQuery.extend.each (http://localhost:52216/admin/Scripts/jquery-1.11.2.js:384:23) at jQuery.fn.jQuery.each (http://localhost:52216/admin/Scripts/jquery-1.11.2.js:136:17) at jgrid.extend.setRowData (http://localhost:52216/admin/Scripts/jqgrid-4.9.1/js/jquery.jqgrid.src.js:5495:9)

在$.fn.jqGrid (http://localhost:52216/admin/Scripts/jqgrid-4.9.1/js/jquery.jqgrid.src.js:2003:14)

发生。

异常发生在getGridRowById中

if (this.p.rowIndexes != null)

代码假定这是jqgrid，但在本例中，这是主窗口，因为它是从jquery.jqgrid.src.js中的第2003行调用的。

return fn.apply(this, $.makeArray(arguments).slice(1));

这发生在github的免费jqgrid中，日期为2015-07-24。在以前的版本中没有发生这种情况。怎么修呢？

对不起，但是在调用堆栈中可以看到，问题发生在调用您的回调函数的内部的setRowData中，回调函数afterSaveFuncAfterAdd在另一个回调函数aftersavefunc中调用。我想你在堆栈里打错电话了。

我建议您验证aftersavefunc (由fullBoolCallback调用)是否正确地将this初始化为网格的DOM。您必须使用.call或.apply来调用任何子函数(例如afterSaveFuncAfterAdd.call(this, otherParameters);)。我想有些电话是没有转发this的。
