Question regarding the client object model. I wrote some client script for a procedure, but i don't know, how can I determine if the list or item has the field available or not? For example:


This code will execute very wel if the field "_dlc_DocID" is available in the list, but it is also possible that this field will not be available because of the feature that is deactivated, then it will throw an error. And nothing will execute further, so i need some kind of a check to see if this field is available or not. Anyone has any idea? I tried:


But no success ... do i miss something?

Here is the whole code:

function CreateLink() {
    var ctx = SP.ClientContext.get_current();
    this.web = ctx.get_web(); 
    this.site = ctx.get_site();
    var listId = SP.ListOperation.Selection.getSelectedList();
    this.list = this.web.get_lists().getById(listId);

    var items = SP.ListOperation.Selection.getSelectedItems(ctx);
    var mijnid = items[0];
    this.listItem = list.getItemById(mijnid.id);

    ctx.load(this.web, 'ServerRelativeUrl');
    ctx.load(this.site, 'ServerRelativeUrl', 'Url');
    ctx.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));

function onQuerySucceeded(sender, args) {

    var title = this.listItem.get_item('FileLeafRef');
    var webRelativeUrl = this.web.get_serverRelativeUrl();
    var siteUrl = this.site.get_url();
    var webAppUrl = siteUrl.replace(webRelativeUrl, "");
    var url;    
    var dlcdocid=this.list.get_fields().getByInternalNameOrTitle("_dlc_DocIdSome");

   .... todo

Found a proper javascript client object model solution for my problem: Here is the solution:

this.listFields = list.get_fields();

And then in the function: onQuerySucceeded

var fieldEnumerator = this.listFields.getEnumerator();
    while (fieldEnumerator.moveNext()) {
        var field = fieldEnumerator.get_current();
        var name = field.get_staticName();
        if (name == "_dlc_DocId") {
            docFeatureEnabled = true;

I hope this helps and can spare some time for people.

string siteUrl = "http://MyServer/sites/MySiteCollection"; 
        ClientContext clientContext = new ClientContext(siteUrl); 
        SP.List List = clientContext.Web.Lists.GetByTitle("my forum"); 
        for (int i = 0; i < list.Fields.Count; i++) 
           if (list.Fields[i].Title == "xyz") 

I have stolen this from https://stackoverflow.com/questions/4401253/check-if-a-list-column-exists-using-sharepoint-client-object-model

  • does list.get_fields() get you anything? you mentioned in your post you had tried this? If it does then you can count the fields that this returns and replace the list.Fields.Count with an interger variable.
