Handel Multiple Click on Elements JQuery

I have experience that user on the page try to click multiple time on the button, in case of page delay, this is a short way to handle such issue.


This will remove all event handlers:

$(element).off().on('click', function() {
    // function body
});

To only remove registered 'click' event handlers:

$(element).off('click').on('click', function() {
    // function body
});

Send E-mail from javascript using REST API - SharePoint

In SharePoint 2013 we can send emails using REST API where we can utilize SP.Utilities.Utility.SendEmail for doing the job. 

Note: The recipient is limited to a valid SharePoint user for security reasons.

function sendEmail(from, to, body, subject) { //Get the relative url of the site var siteurl = _spPageContextInfo.webServerRelativeUrl; var urlTemplate = siteurl + "/_api/SP.Utilities.Utility.SendEmail"; $.ajax({ contentType: 'application/json', url: urlTemplate, type: "POST", data: JSON.stringify({ 'properties': { '__metadata': { 'type': 'SP.Utilities.EmailProperties' }, 'From': from, 'To': { 'results': to }, 'Body': body, 'Subject': subject } }), headers: { "Accept": "application/json;odata=verbose", "content-type": "application/json;odata=verbose", "X-RequestDigest": jQuery("#__REQUESTDIGEST").val() }, success: function(data) { alert('Email Sent Successfully'); }, error: function(err) { alert('Error in sending Email: ' + JSON.stringify(err)); } }); } $(document).ready(function () { SP.SOD.executeFunc('sp.js', 'SP.ClientContext', SendEmails); }); function SendEmails() { var from = 'info@domain.com', to = 'toUser@domain.com', body = 'Email using REST API', subject = 'Email FYI'; sendEmail(from, to, body, subject); }

Note: You can add 'CC' and 'BCC' property also to send email, property 'results' having array.

Remove a specific class from all child elements, and add new class

$('#parentDiv').find("*").removeClass("old-class").addClass("new-class");

Useful Windows Command Prompt Commands

3. See PC driver list :You can see all the drivers installed on your computer.
c:\>driverquery

4. Send an output to clipboard: Save the output of a command.

5. Create Wi-Fi hotspot right from the command prompt
Before opening the Command Prompt to execute the commands needed for this, you need to open Control Panel and find Change adapter settings in the Network and Sharing option. There, click on the connection you are using and click on Properties. Now find the sharing tab and check the option “Allow other network users to connect through this computer’s internet connection.”

-Open the Command Prompt with administrative privileges and enter the following command to enabled hotspot:
c:\> netsh wlan set hostednetwork mode=allow ssid=Youthotspotname key=yourpassword

-start the Wi-Fi hotspot
c:\>netsh wlan start hostednetwork

-To stop it, simply enter this command:
c:\>netsh wlan stop hostednetwork
