本来是需要隐藏同一页面的 Related List Item，找答案的时候顺便想到要去掉那个Save Draft 按钮，于是就在那个页面的源代码中去掉了一个 <td>,轻松搞定。下面是如何隐藏related list item

If you only want to hide the link button in a Workflow Task form, you can edit this form in SPD. After a new SPD workflow is created, there will create a new task form for this workflow in workflows folder: Open the Site using the SharePoint Designer >expand the Workflows in Folder List>expand the workflow that you created, you will find a new form page (“TaskName”.aspx) under the workflow> double-click the page and search for “Related list item” in Code view, and then set the <tr> tag to <tr style=”visibility:hidden”>. This will hide the “Related list item” in task form.

Hope it can help you.

终于找到了，做个备份，防止以后忘掉

figure it out by using SharePoint manager to look inside:

对于sharepoint的list，有时候需要用户填写的条目比较多，sharepoint本身并没有比较好的前端验证的功能，可以通过工作流在后台进行验证，不过这样就得在用户提交表单之后了，很不方便，如果可以通过JavaScript在客户端对用户所填写内容进行实时验证就很完美了。把网上搜罗到的方法逐个拿来折腾，最后终于找到个可以用的。下图是效果

具体做法是新建一个CEWP，然后把如下代码贴进去

<script language=”javascript” type=”text/javascript”>

function PreSaveAction()
{
    var date1 = getTagFromIdentifierAndTitle(“INPUT”,”DateTimeFieldDate”,”Start Date”); 
    var date2 = getTagFromIdentifierAndTitle(“INPUT”,”DateTimeFieldDate”,”Due Date”);
    var arrDate1 = date1.value.split(“/”);
    var useDate1 = new Date(arrDate1[2], arrDate1[1]-1, arrDate1[0]);
    var arrDate2 = date2.value.split(“/”);
    var useDate2 = new Date(arrDate2[2], arrDate2[1]-1, arrDate2[0]);
    if(useDate1 > useDate2)
    {
        alert(“The end date cannot happen earlier than the start date”);
        return false; // Cancel the item save process
    }
    return true;  // OK to proceed with the save item
}

function getTagFromIdentifierAndTitle(tagName, identifier, title) {
var len = identifier.length;
var tags = document.getElementsByTagName(tagName);
for (var i=0; i < tags.length; i++) {
var tempString = tags[i].id;
if (tags[i].title == title && (identifier == “” || tempString.indexOf(identifier) == tempString.length – len)) {
return tags[i];
}
}
return null;
}

</script>
