【SharePoint】SharePoint 2013 使用PreSaveAction自定义客户端验证

使用PreSaveAction函数实现客户端自定义验证。

例：【项目编号】为空时，必须填写【责任者】项。（其中【项目编号】为单行文本框，【责任者】为用户/组选择框。）

function PreSaveAction(){
    var porjectNo = $("[id$=TextField][Title='项目编号']").val();
    var peoplePickerDiv = $("[id$='ClientPeoplePicker'][title='责任者']");
    peoplePickerDiv.next(".ms-formvalidation").remove();

    if (porjectNo == "") {
        var spPeoplePicker = SPClientPeoplePicker.SPClientPeoplePickerDict[peoplePickerDiv[0].id];

        if (spPeoplePicker.IsEmpty()) {
            var errorHtml = '<span class="ms-formvalidation sp-peoplepicker-errorMsg"><span role="alert">项目编号为空时，请填写【责任者】。<br></span></span>';
            peoplePickerDiv.after(errorHtml);
            return false;
        }
    }

    return true;
};
