在选项中添加图像 [英] Adding image in option

问题描述

当我打开列表并使用 awesomplete自动完成插件时，我想在选项左侧添加图片，我想添加一张图片，向您展示我想做的事情.

I want to add a image left of my option when my list opened and I'm using awesomplete autocomplete plugin and I'd like to add a picture to show you what I want to do.

我尝试添加内联CSS，但没有任何变化

I try to add inline css but nothing change

$(document).ready(function() {
  $('.awesomplete').on('awesomplete-select', function() {
    var $this = $(this),
      $sibling = $this.next();
    if ($sibling.attr('id') == 'mylist') {
      setTimeout(function() {
        var val = $this.find('input').val();
        var dataLink = $sibling.find('option:contains("' + val + '")').data('link');
        //console.log(dataLink);
        location.href = dataLink;
      }, 500);
    }
  });
});

  border-radius: .3em;

推荐答案

您可以覆盖将图片放在标签前的单个项目的创建，例如:

You could override the creation of single item putting an image before the label, like:

var awesomplete = new Awesomplete(input, {
   item: myItemFunc
});;

function myItemFunc(text, input){
    //return the html to render an item
}

有关完整示例，请参见以下内容:

See following for a complete example:

var imgList = new Object();
imgList["Ada"] = "http://www.maglioccola.com/images/add-1.png";
imgList["Java"] = "http://www.maglioccola.com/images/add-2.png";
imgList["JavaScript"] = "http://www.maglioccola.com/images/add-3.png";
imgList["Brainfuck"] = "http://www.maglioccola.com/images/add-4.png";
imgList["LOLCODE"] = "http://www.maglioccola.com/images/add-4.png";
imgList["Node.js"] = "http://www.maglioccola.com/images/add-4.png";
imgList["Ruby on Rails"] = "http://www.maglioccola.com/images/add-4.png";

$(document).ready(function() {
  var input = document.getElementById("my-input");
  var awesomplete = new Awesomplete(input, {
    item: myItemFunc
  });;
});

function myItemFunc(text, input){
  return Awesomplete.$.create("li", {
    innerHTML: createItem(text,input),
    "aria-selected": "false"
  });
}

function createItem(text, input){
  var img = document.createElement("img");
  img.style.height = '16px';
  img.src = imgList[text.label];
  var html = img.outerHTML + " " + text.label;
  return html;
}
