防止双重会议共享点日历​​csom

Question

如果日期和时间已在日历中预订，我试图制作它不要预订，我使用此代码并且没有显示任何内容？任何Sugestions？

 var context = SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists();
var targetList;

function createItem（）{     targetList = list.getByTitle（＆＃34; AppbokningarList＆＃34;）;

    var listItemCreation = new SP.ListItemCreationInformation();
    var newItem = targetList.addItem(listItemCreation);
    var listItemTitle = document.getElementById('Textrubrik').value;
    alert(listItemTitle);
    var listItemCustom = document.getElementById('datepicker').value;
    alert(listItemCustom);
    var listItemFromTime = document.getElementById('timepicker').value;
    alert(listItemFromTime);
    var listItemtoDate = document.getElementById('datepickerto').value;
    alert(listItemtoDate);
    var listItemToTime = document.getElementById('timepickerTo').value;
    alert(listItemToTime);
    var listItemBeskrivning = document.getElementById('Textbeskrivning').value;
    alert(listItemBeskrivning);
    newItem.set_item('Title', listItemTitle);
    var result = listItemCustom + " " + listItemFromTime;
    newItem.set_item('EventDate', result);
    var result2 = listItemtoDate + " " + listItemToTime;
    newItem.set_item('EndDate', result2);
    newItem.set_item('Description', listItemBeskrivning);

    var camlQuery = new SP.CamlQuery();
    camlQuery.set_viewXml("<Where><Geq><FieldRef Name='EventDate' /><Value Type='DateTime'>" + result + "</Value></Geq><Leq><FieldRef Name='EndDate' /><Value Type='DateTime'>" + result2 + "</Value></Leq><FieldRef Name='RecurrenceID' /></Where>");

    this.collListItem = targetList.getItems(camlQuery);
    context.load(collListItem);

    var property = new SP.EventProperties();
    if (collListItem > 0) {
        property.cancel = true;
    }
    newItem.update();
    context.load(newItem);

    context.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded),Function.createDelegate(this, this.onQueryFailed));

}

function onQuerySucceeded（sender，args）{

var succeded = "Mötet är nu bokat!";
alert(succeded);

}

function onQueryFailed（sender，args）{

var failed = "Redan bokat!";
alert(failed);

}

查看所有set_items。很可能您的日期字段需要一个实际日期对象才能成功存储到SP。

var currDate = new Date();
listItem.set_item('DateColumn',currDate);
listItem.update();
