javascript - Jquery Autocomplete _renderItem does not work when Function is called a second time -


i wanted generate 2 input fields autocomplete generates icons. used _renderitem realised, - calling autocomplete using single class multiple input fields - second field not call _renderitem function:

see here: 

var $project = $('.project');      var projects = [{      value: "jquery",      label: "jquery",      desc: "the write less, more, javascript library",      icon: "jquery_32x32.png"    },    {      value: "jquery-ui",      label: "jquery ui",      desc: "the official user interface library jquery",      icon: "jqueryui_32x32.png"    },    {      value: "sizzlejs",      label: "sizzle js",      desc: "a pure-javascript css selector engine",      icon: "sizzlejs_32x32.png"    }  ];    $project.autocomplete({    minlength: 0,    source: projects,    focus: function(event, ui) {      this.val(ui.item.label);      return false;    }  });    $project.data("ui-autocomplete")._renderitem = function(ul, item) {      var $li = $('<li>'),      $img = $('<img>');        $img.attr({      src: 'https://jqueryui.com/resources/demos/autocomplete/images/' + item.icon,      alt: item.label    });      $li.attr('data-value', item.label);    $li.append('<a href="#">');    $li.find('a').append($img).append(item.label);      return $li.appendto(ul);  };
<script src="https://code.jquery.com/jquery-1.11.0.min.js"></script>  <link href="https://code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.min.css" rel="stylesheet" type="text/css" />  <script src="https://code.jquery.com/ui/1.10.4/jquery-ui.min.js"></script>    <div id="project-label">this 1 works:</div>  <input class="project">  <br />  <br />  <br />  <br />    <div id="project-label">this 1 not show images in list:</div>  <input class="project">

how comes in second autocomplete input-field images not shown. how can working. since in website using php generate fields automatically , have 1 autocompletefunction overall, calling autocomplete via class. there possibility? helping.

just wrap each called each item in collection.

iterate on jquery object, executing function each matched element.

var $project = $('.project');      var projects = [{      value: "jquery",      label: "jquery",      desc: "the write less, more, javascript library",      icon: "jquery_32x32.png"    },    {      value: "jquery-ui",      label: "jquery ui",      desc: "the official user interface library jquery",      icon: "jqueryui_32x32.png"    },    {      value: "sizzlejs",      label: "sizzle js",      desc: "a pure-javascript css selector engine",      icon: "sizzlejs_32x32.png"    }  ];    $project.autocomplete({    minlength: 0,    source: projects,    focus: function(event, ui) {      this.val(ui.item.label);      return false;    }  });    $project.each(function() {    var $proj = $(this);        $proj.data("ui-autocomplete")._renderitem = function(ul, item) {      var $li = $('<li>'),        $img = $('<img>');          $img.attr({        src: 'https://jqueryui.com/resources/demos/autocomplete/images/' + item.icon,        alt: item.label      });        $li.attr('data-value', item.label);      $li.append('<a href="#">');      $li.find('a').append($img).append(item.label);        return $li.appendto(ul);    };  });
<script src="https://code.jquery.com/jquery-1.11.0.min.js"></script>  <link href="https://code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.min.css" rel="stylesheet" type="text/css" />  <script src="https://code.jquery.com/ui/1.10.4/jquery-ui.min.js"></script>    <div id="project-label">this 1 works:</div>  <input class="project">  <br />  <br />  <br />  <br />    <div id="project-label">this 1 not show images in list:</div>  <input class="project">

android - InAppBilling registering BroadcastReceiver in AndroidManifest -
