## 搜索模式
### 默认搜索
:::demo 默认按照`name`进行搜索
```html
<div id="demo1" class="xm-select-demo"></div>
<script>
var demo1 = xmSelect.render({
el: '#demo1',
filterable: true,
data: [
{name: '水果', value: 1},
{name: '蔬菜', value: 2},
{name: '桌子', value: 3},
{name: '北京', value: 4},
]
})
</script>
```
:::
### 重写搜索方法
:::demo
```html
<div id="demo2" class="xm-select-demo"></div>
<script>
var demo2 = xmSelect.render({
el: '#demo2',
filterable: true,
filterMethod: function(val, item, index, prop){
if(val == item.value){//把value相同的搜索出来
return true;
}
if(item.name.indexOf(val) != -1){//名称中包含的搜索出来
return true;
}
return false;//不知道的就不管了
},
data: [
{name: '水果', value: 1},
{name: '蔬菜', value: 2},
{name: '桌子', value: 3},
{name: '北京', value: 4},
]
})
</script>
```

### 搜索延迟
为了提高有效搜索, 当停止输入`500ms`后才开始进行过滤搜索, 当然这个`500`你也可以进行修改
:::demo `delay: 2000` 输入停止2s后进行搜索过滤
```html
<div id="demo3" class="xm-select-demo"></div>
<script>
var demo3 = xmSelect.render({
el: '#demo3',
filterable: true,
delay: 2000,
data: [
{name: '水果', value: 1},
{name: '蔬菜', value: 2},
{name: '桌子', value: 3},
{name: '北京', value: 4},
]
})
</script>
```

### 自定义搜索 (远程搜索)
第一步: 需要先开启搜索 `filterable: true,`
第二步: 开启自定义搜索 `remoteSearch: true`
第三部: 重写搜索回调
简单吧, 记得Star ^_^
:::demo `render`后, 就会进行一次回调, 用于渲染第一次数据
```html
<div id="demo4" class="xm-select-demo"></div>
<script>
var demo4 = xmSelect.render({
el: '#demo4',
filterable: true,
remoteSearch: true,
remoteMethod: function(val, cb, show){
//这里模拟3s后返回数据
setTimeout(function(){
//需要回传一个数组
cb([
{name: '水果' + val, value: val + 1},
{name: '蔬菜' + val, value: val + 2, selected: true},
{name: '桌子' + val, value: val + 3},
{name: '北京' + val, value: val + 4},
])
}, 3000)
},
data: []
})
</script>
```

### 搜索完成回调
:::demo
```html
<div id="demo6" class="xm-select-demo"></div>
<script>
var demo6 = xmSelect.render({
el: '#demo6',
filterable: true,
filterDone: function(val, list){
alert(`搜索完毕, 搜索关键词: ${val}, 过滤数据: ${list.length}个`)
},
data: [
{name: '水果', value: 1},
{name: '蔬菜', value: 2},
{name: '桌子', value: 3},
{name: '北京', value: 4},
]
})
</script>
