我试图检查一个条件..我需要检查两个条件

请多多支持

Answer 1

您可以使用以下代码来限制重复输入：

<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, textStatus, errorThrown) {
                    alert(textStatus);
                }
            })
        
                           return check;
        }
</script>

注意：您需要更改以下内容：

在 var DateId = $("input[title='Date_Req']").val() 中，将“Date_Req”更改为您的日期列名称；
在 $.ajax() 中，将 url 部分

结果是这样的：

<script type="text/javascript">
       function PreSaveAction() {
           var check = false;
           //var listid = _spPageContextInfo.pageListId.replace('{', '').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 + "'",                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, textStatus, errorThrown) {
                   alert(textStatus);
               }
           })
       
                          return check;
       }
</script>```
