calling a php script using $.POST in javascript -


i have html form textarea , button calls function below when part of text selected. de id of clicked button , selected text want call php script post method.

$(document).ready(function() {     $(".postbit_buttons").on("click", ".quoted_clicked", function() {         var post = this.id;         var selected = getselectedtext();         alert(" post = " + post + " seleted text = " + selected);         $.post("test_quoted.php", {                 pid: post,                 selection: selected             })             .done(function() {                 alert("done")             });     }); });

function getselectedtext() selection found here. first alert shown correct information. however, after clicking ok following error message on browser console:

typeerror: 'collapse' called on object not implement interface selection.

i have used similar construct in part of forum software of part, , works.

i have pain in eyes of staring @ this, cannot find cause. there can me on this?

@rory code of function getselectedtext() is:

function getselectedtext() {   var selectedtext=(         window.getselection         ?             window.getselection()         :             document.getselection             ?                 document.getselection()             :                 document.selection.createrange().text      );  if(!selectedtext || selectedtext=="")  {     if(document.activeelement.selectionstart)     {      selectedtext = document.activeelement.value.substring(           document.activeelement.selectionstart           . document.activeelement.selectionend);     }  }  return selectedtext; }

thanks rory's question tried things out. discovered variable "selected" in selected text stored cause of error. use following version of getselectedtext():

function getselectedtext () {     if (window.getselection) {  // browsers, except ie before version 9         var range = window.getselection ();         return range.tostring ();     }      else {         if (document.selection.createrange) { // internet explorer             var range = document.selection.createrange ();             return range.text;         }     } }

and works!! sorry bothering you. practice programming since 1968, 100% scientific computing fortran. javascript new me.
