php - Handling whitespace with jQuery .val() method. (Using Codeigniter) -

How do I get confused that the .val () method in jQuery handles whitspeak (if it's a jQuery problem)

My example is using an AJAX suggestions box feature which I am slowly developing. It uses Codeigniter as the framework.

I have this jQuery code:

  $ (document) .ready (function () {$ ("# suggestbox"). () "$" (" ("#"). ("(" "Search"); if ($ ("$ searchboxinput") .val (. Length == 0) {$ ("# suggestbox"). FadeOut (100);} and {$ ("# Suggest Box") .Phidin (100); $ ("#sugresultcontain"). Load ('http: // localhost / ajaxtest / ajaxhandle / suggest /' + $ ("#searchboxinput") .val () + '# Loadsuggest');}}}};});   
 '#suggestboxinput' is a text input as shown:  
 < 
 
 
 
 Input ID = "searchbuttoninput" name = "" type = "button" value = "Go"> 
  
 gt; id id = "suggesthead" & gt; & lt; div; ; Suggestion: & lt; / Div & gt; & Lt; Div id = "sugresultcontain" & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt;   
 I then (using code igniter) is a method that is shown as .load ():  
  public function suggestions ( $ Q = '') {$ Suggestion = $ it- & gt; Ajax_handle- & gt; suggestion (); ($ I = 0; $ i & lt; Count ($ suggestion); $ i ++) {$ db [$ i] = $ suggestion [$ i] ['first name'] ''. $ Suggestion is [$ i] ['nickname']; } If (strollon ($ q)> gt; {$ sugstr = ''; $ E = 0; ($ F = 0; $ f & lt; count ($ db); $ f ++) {if (stroller ($ q) == stroller (substart ($ db [$ f], 0, strlen ($ q) )) {$ Shugerslutt [$ E] = $ db [$ f]; $ E ++; }} If (isset ($ sugresult)) {$ data ['sugresult'] = $ $ sugresult; $ This- & gt; Load-> See ('ajaxref / suggest', $ data); } And {$ this- & gt; Load-> See ('ajaxref / suggest'); }} And {$ this-> Load-> See ('ajaxref / suggest'); }}   
 This work is almost done, if I load the page, using text input, showing the names from the database (according to the text field). It works fine if I type the first name and how many spaces I leave after the field does not seem to matter (which is right).  
 However, the problem is in typing aliases only after one place (Dominic Sauer) or even the first letter or last name (Dominic S). No name is shown in the suggestion box.  
 I had read that using the '+' symbol in the input box would work. I tested it, and it worked (Dominic + produces Dominic Pigs in the hourly suggestion box) However clearly , I can not write '+' to use users everywhere  
 So I'm thinking how I handle it? I am studying a lot, but I am not getting any solution.  
 Thank you.   
 
 
 Try the method:  
 
 The startup of the strings on the whitespace and Remove from the end.   
  var txt = $ .trim ($ ("# searchboxinput"). Val ()). Replace ('', '+')
