SHAREPOINT - 限制重复输入

如何解决SHAREPOINT - 限制重复输入

伙计们需要以下场景的支持 我有一份带有日期和时间的预订清单。我想按日期和时间限制重复条目 我已经尝试了其余的 Api 代码，但它不起作用.. 请支持在我的代码下方查找

我试图用一个条件检查..我需要用两个条件检查

请支持

解决方法

您可以使用以下代码限制重复输入：

<script type="text/javascript">
        function PreSaveAction() {
            var check = false;
            //var listid = _spPageContextInfo.pageListId.replace('{','').replace('}','');
            var DateId = $("input[title='Date_Req']").val();
            alert(DateId);
            $.ajax({
                //replace the rest api to filter items based on your files
                url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists//GetByTitle('List0325')/items?$select=ID,Date_Req,Title&$orderby=ID desc&$filter=Date_Req eq '"  + DateId + "'",type: 'GET',async: false,headers: {
                    "accept": "application/json;odata=verbose","content-type": "application/json;odata=verbose",},success: function (data,textStatus,jqXHR) {
                    var count = data.d.results.length;
                    if (count < 1) {
                        check = true;
                    } else {
                        alert('Dear Employee,there is no slot available during this period');
                    }
                },error: function (jqXHR,errorThrown) {
                    alert(textStatus);
                }
            })
        
                           return check;
        }
</script>

注意：您需要更改以下内容：

1. 在 var DateId = $("input[title='Date_Req']").val() 中，将“Date_Req”更改为您的日期列名称；
2. 在 $.ajax() 中，将 url 部分中的列表标题和列名称更改为您的名称

结果是这样的：

,

<script type="text/javascript">
       function PreSaveAction() {
           var check = false;
           //var listid = _spPageContextInfo.pageListId.replace('{','');
           var DateId = $("input[Title*='Req_Date']").val();
           var TimeID= $("select[Title*='Req_Time'] option:selected").text();


           alert(DateId);
           alert(TimeID);
           $.ajax({
 //replace the rest api to filter items based on your files 
 url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists//GetByTitle('Discussion2')/items?$select=ID,Req_Date,Req_Time,Title&$orderby=ID desc&$filter= Req_Date eq '" + DateId + "' and Req_Time eq '" + TimeID + "'",headers: {
                   "accept": "application/json;odata=verbose",jqXHR) {
                   var count = data.d.results.length;
                   if (count < 1) {
                       check = true;
                   } else {
                       alert('Dear Employee,there is no slot available during this period');
                   }
               },errorThrown) {
                   alert(textStatus);
               }
           })
       
                          return check;
       }
</script>```
