重定向自动完成

标签： javascript jquery

我正在使用awesomplete autocomplete plugin，我需要重新定位我在单击任何结果时选择的项目，例如我写了一个Javascript，点击它之后，它必须重定向我想要的任何页面。我请参阅events，但我不知道如何使用它

我的结构

＆＃13;
＆＃13; 
$(document).ready(function() {

});
＆＃13; 
.awesomplete > ul {
	border-radius: .3em;
	margin: .2em 0 0;
	background: hsla(0,0%,100%,.9);
	background: linear-gradient(to bottom right, white, hsla(0,0%,100%,.8));
	border: 1px solid rgba(0,0,0,.3);
	box-shadow: .05em .2em .6em rgba(0,0,0,.2);
	text-shadow: none;
}

@supports (transform: scale(0)) {
	.awesomplete > ul {
		transition: .3s cubic-bezier(.4,.2,.5,1.4);
		transform-origin: 1.43em -.43em;
	}
	
	.awesomplete > ul[hidden],
	.awesomplete > ul:empty {
		opacity: 0;
		transform: scale(0);
		display: block;
		transition-timing-function: ease;
	}
}

	/* Pointer */
	.awesomplete > ul:before {
		content: "";
		position: absolute;
		top: -.43em;
		left: 1em;
		width: 0; height: 0;
		padding: .4em;
		background: white;
		border: inherit;
		border-right: 0;
		border-bottom: 0;
		-webkit-transform: rotate(45deg);
		transform: rotate(45deg);
	}

	.awesomplete > ul > li {
		position: relative;
		padding: .2em .5em;
		cursor: pointer;
	}
	
	.awesomplete > ul > li:hover {

		color: black;
	}
	
	.awesomplete > ul > li[aria-selected="true"] {
		background: hsl(205, 40%, 40%);
		color: white;
	}
	
		.awesomplete mark {
			background: hsl(65, 100%, 50%);
		}
		
		.awesomplete li:hover mark {
			background: hsl(68, 100%, 41%);

您可以像这样使用 awesomplete-selectcomplete 

document.getElementById('my-input').addEventListener('awesomplete-selectcomplete',function(){
  alert(this.value); 
  //TODO HERE
});
.awesomplete > ul {
	border-radius: .3em;
	margin: .2em 0 0;
	background: hsla(0,0%,100%,.9);
	background: linear-gradient(to bottom right, white, hsla(0,0%,100%,.8));
	border: 1px solid rgba(0,0,0,.3);
	box-shadow: .05em .2em .6em rgba(0,0,0,.2);
	text-shadow: none;
}

@supports (transform: scale(0)) {
	.awesomplete > ul {
		transition: .3s cubic-bezier(.4,.2,.5,1.4);
		transform-origin: 1.43em -.43em;
	}
	
	.awesomplete > ul[hidden],
	.awesomplete > ul:empty {
		opacity: 0;
		transform: scale(0);
		display: block;
		transition-timing-function: ease;
	}
}

	/* Pointer */
	.awesomplete > ul:before {
		content: "";
		position: absolute;
		top: -.43em;
		left: 1em;
		width: 0; height: 0;
		padding: .4em;
		background: white;
		border: inherit;
		border-right: 0;
		border-bottom: 0;
		-webkit-transform: rotate(45deg);
		transform: rotate(45deg);
	}

	.awesomplete > ul > li {
		position: relative;
		padding: .2em .5em;
		cursor: pointer;
	}
	
	.awesomplete > ul > li:hover {
		background: hsl(200, 40%, 80%);
		color: black;
	}
	
	.awesomplete > ul > li[aria-selected="true"] {
		background: hsl(205, 40%, 40%);
		color: white;
	}
	
		.awesomplete mark {
			background: hsl(65, 100%, 50%);
		}
		
		.awesomplete li:hover mark {
			background: hsl(68, 100%, 41%);
		}
		
		.awesomplete li[aria-selected="true"] mark {
			background: hsl(86, 100%, 21%);
			color: inherit;
		}
<input class="awesomplete dropdown-input" list="mylist" id="my-input" />
<datalist id="mylist">
	<option data-link="http://www.google.com">Ada</option>
	<option data-link="http://www.yahoo.com">Java</option>

获取所选项目的属性没有原生支持。

要绑定事件，请使用所选选择器上的on功能。

要获取data-link属性，您需要获取datalist并找到带有文字值的option。

Awesomplete是两次触发事件 - 一次在输入字段上，一次在包含div上。我正在通过检查它的兄弟是datalist来监听div上的事件。完成后，我会使用option选择器找到所需的:contains，并传入输入字段值。

我必须将它包装在setTimeout函数中，因为此时，Awesomplete尚未填充输入字段的value属性。

$(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);
    }
  });
});
.awesomplete > ul {
	border-radius: .3em;
	margin: .2em 0 0;
	background: hsla(0,0%,100%,.9);
	background: linear-gradient(to bottom right, white, hsla(0,0%,100%,.8));
	border: 1px solid rgba(0,0,0,.3);
	box-shadow: .05em .2em .6em rgba(0,0,0,.2);
	text-shadow: none;
}

@supports (transform: scale(0)) {
	.awesomplete > ul {
