验证在列表框中呈现的文本框

Question

`

   <listitem self="@{each='idSequence'}" value="@{idSequence}">
        <listcell>
            <intbox value="@{idSequence.currentIndex,save-when='Save.onClick'}" constraint="no empty" />
        </listcell>
        <listcell>
            <intbox value="@{idSequence.startIndex}" onBlur="validateStartIndex(self)" constraint="no empty" />
        </listcell>

On click of the save button i need to check that the currentIndex is always greater than the startIndex ....

The way i do it currently is to use getSelectedItems and iterate over it to do the validation.

Is there a alternate or better way of doing the same ?

您可以使用onBindingSave事件来执行此操作，请查看Databinding Validation的文档 。
