Get the sharepoint form Field ID using javascript and column Internal Name.

Question

_{Sunday, July 8, 2018 6:45 PM}

Hello,

I have been reading this post: https://social.technet.microsoft.com/Forums/sharepoint/en-US/236ebd74-8d1d-45fd-a738-24aeefd0b2d5/get-the-sharepoint-form-field-id-using-javascript?forum=sharepointgeneralprevious

The reason is I would like to get the textbox (<input />) using the Internal name of the column instead the title as I have read in that post.

or Is there any way to transfrom the Internal name (Eg. "First Name User") to get the ID of this field? 

<input type="text" value="" maxlength="25" id="First_x0020_Name_x0020_User12c0b2-b652-47f1-8adb-af671dabac2f_$TextField" title="First Name:" style="ime-mode : " class="ms-long ms-spellcheck-true">

Thank you!

Hi,

You could do this by JSOM if you don’t want to use jQuery as you shread.

<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">
<script type="text/ecmascript" language="ecmascript">

    var fieldCollection;
    var oneField = null;
    function runCode() {
        var clientContext = SP.ClientContext.get_current();
        if (clientContext != undefined && clientContext != null) {
            var webSite = clientContext.get_web();
            taskList = webSite.get_lists().getByTitle("Tasks");

            fieldCollection = taskList.get_fields();
            this.oneField = fieldCollection.getByInternalNameOrTitle("Title");

            this.oneField.set_description("MyNewFieldDescription");
            this.oneField.update();

            clientContext.load(this.fieldCollection);
            clientContext.load(this.oneField);
            clientContext.executeQueryAsync(Function.createDelegate(this, this.OnLoadSuccess), Function.createDelegate(this, this.OnLoadFailed));
        }
    }

    function OnLoadSuccess(sender, args) {
        var fieldInfo = '';
        fieldInfo += 'Field Title: ' + oneField.get_title() + '\n' + 'Description: ' + oneField.get_description() + '\n';
        alert(fieldInfo);
    }

    function OnLoadFailed(sender, args) {
        alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
    }
</script>

    <input id="Button1" type="button" value="Run Code" onclick="runCode()" />

</asp:Content>
