2. // Load the links on app load.$(document).ready(function()

3. {   

4.  hostweblink = decodeURIComponent(       

5.  getQueryStringParameter(“SPHostUrl”));    

6. applink = decodeURIComponent(        

7. getQueryStringParameter(“SPAppWebUrl”));

8. //Assign Click event on button   

9.  $(“# deletecolumn”).click(function(event)    

10. {        

11. deletecolumn(); event.preventDefault();    

12. });    

13. varscriptlink = hostweblink + “/_layouts/15/”;    

14. $.getScript(scriptlink + “SP.RequestExecutor.js”);});

15. //function to retrive the clean linkfunctiongetQueryStringParameter(paramvalue)

16. {        

17. varparamval = document.URL.split(“?”)[1].split(“&”);

18. for (vari = 0; i < paramval.length; i = i + 1)        

19. {            

20. var paramval1 = paramval[i].split(“=”); if (paramval1[0] == paramvalue) return paramval1[1];       

21.  }    }

22. // Delete columnfunctiondeletecolumn()

23. {    

24. vardeletecolumnname = document.getElementById(“deletecolumnname”).value;    

25. var play;    

26. play = new SP.RequestExecutor(applink);    

27. play.executeAsync    

28. ({       

29.  url: applink + “/_api/SP.AppContextSite(@target)/web/lists/getbytitle(‘DevData’)/fields/getbytitle(‘” + deletecolumnname + “‘)?@target='” + hostweblink + “‘”,
