javascript - xmlhttp.open does not seem to do anything in MVC structure -


i'm trying add auto-complete function text field. used work, switched mvc structure , can't work.

php/html:

echo '<br><br>add member:<br>'     . '<form method="post"><input type="text" name="username" oninput="findusers(this.value)" list="livesearch">'     . '<datalist id="livesearch"></datalist>'     . '<input type="submit" value="add">'     . '</form>';

javascript:

<script> function findusers(str) {     if (str == "") {         document.getelementbyid("livesearch").innerhtml = "no suggestions";         xmlhttp.send();     } else {         if (window.xmlhttprequest) {                 // code ie7+, firefox, chrome, opera, safari                 xmlhttp = new xmlhttprequest();         } else {                 // code ie6, ie5                 xmlhttp = new activexobject("microsoft.xmlhttp");         }         xmlhttp.onreadystatechange = function() {                 if (xmlhttp.readystate == 4 && xmlhttp.status == 200) {                         document.getelementbyid("livesearch").innerhtml = xmlhttp.responsetext;                 }         };         xmlhttp.open("get","/user/search/?q="+str,true);         xmlhttp.send();     } } </script>

/user/search opens function called search in class user in usercontroller.php file

class usercontroller extends controller { public function search()     {         $response = "hello";         echo $response;     } }

so should put "hello" message in livesearch datalist. reason nothing happening. if replace xmlhttp.open window.open, page load , shows hello message. not want.

figured out exact problem:

my xmlhttp.responsetext returning header of website, loaded in mvc structure.

how work around this? option edit string , last part in javascript? or there better solutions?

used javascript grab last part of string (so without header) it's supposed now, feels pretty "dirty" solution.

also had add <option value=""> tag, in code, not in testcode.

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

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
