无法在处理onPaging事件的函数中获取rowNum [英] Trouble with getting rowNum inside the function that handles onPaging event

问题描述

当我在分页组合框中更改rowNum时(请参见下文)

When I change the rowNum in paging combobox (see below)

我想找出选择了哪个号码，所以我决定使用下一个方法:

I want to find out which number was selected so I have decided to use the next approach:

onPaging : function(pgButton) {
  onPagingHandler(pgButton);
}

...

function onPagingHandler(pgButton) {
  if (pgButton != "records"){
    return;
  }
  alert($("#gridId").getGridParam('rowNum'));
}

问题是当我在组合框中选择说 10 时，现在我选择说 30 ，在事件处理程序中，此代码$("#gridId").getGridParam('rowNum')仍然给我以前的提示值( 10 ).为什么没有给我 30 ，我该如何解决?

The issue is when I got say 10 selected in the combobox and now I am selecting say 30, inside the event handler this code $("#gridId").getGridParam('rowNum') still give me previous value (which is 10). Why doesn't it give me 30 and how can I fix it?

推荐答案

您必须直接从select中获取值:

You have to get the value directly from the select:

onPaging : function(pgButton) {
    if (pgButton != "records"){
        return;
    }

    var newRowNum = $(".ui-pg-selbox", this.p.pager).val();
}
