i guess you're looking this:

$(document).ready(function() {     $("#btnselect").click(function() {        var $area = $("textarea.editor");        var area = $area.get()[0];        var s = area.selectionstart;        var e = area.selectionend;        if (s == e) return;        var text = $area.val();        var before = s > 0 ? text.substr(0, s) : "";        var selection = text.substr(s, e - s);        var after = e < text.length - 1 ? text.substr(e) : "";                selection = "<div id=\"selected\">" + selection + "</div>";        $area.val(before + selection + after);        return false;     });  });
html,  body {     width: 100%;     height: 100%;     padding: 0px;     margin: 0px;     font-family: helvetica, arial, sans-serif;     -moz-osx-font-smoothing: grayscale;     -webkit-font-smoothing: antialiased;     background-color: #fafafa;  }    .container {     position: relative;     width: 100%;     max-width: 500px;     margin: 0px auto;     margin-top: 30px;  }    .editor {     float: left;     width: 100%;     padding: 30px;     box-sizing: border-box;     -webkit-box-sizing: border-box;  }    .editbuttons {     width: 100%;     float: left;     margin-bottom: 15px;  }    .editbuttons {     text-decoration: none  }    #btnselect {     padding: 5px;     border-radius: 3px;     -webkit-border-radius: 3px;     background-color: blue;     position: relative;     max-width: 150px;     text-align: center;     color: #ffffff;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div class="container">     <div class="editbuttons">        <a href="" id="btnselect">select</a>     </div>     <textarea class="editor" id="editor">select text. , click blue button. should add following div tag this: <div class="selected">select text.</div> </textarea>  </div>

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
