赋值与取值

给多选赋值

函数setValue(array), 动态赋值多选选中的数据, array可以是value数组, 也可以是完整的object数组

:::demo

<div id="demo1" class="xm-select-demo"></div>
<br/><br/>
<button class="btn" id="demo1-test1">赋值张三</button>
<button class="btn" id="demo1-test2">赋值张三(value方式)</button>
<button class="btn" id="demo1-test3">追加赋值李四</button>
<br/><br/>
<button class="btn" id="demo1-test4">清除李四</button>
<button class="btn" id="demo1-test5">清空</button>
<pre id="demo1-result"></pre>

<script>
var demo1 = xmSelect.render({
    el: '#demo1', 
    data: [
        {name: '张三', value: 1},
        {name: '李四', value: 2},
        {name: '王五', value: 3},
    ]
})

document.getElementById('demo1-test1').onclick = function(){
    demo1.setValue([
        {name: '张三', value: 1},
    ])
};

document.getElementById('demo1-test2').onclick = function(){
    demo1.setValue([ 1 ])
};

document.getElementById('demo1-test3').onclick = function(){
    demo1.append([ 2 ]);
};

document.getElementById('demo1-test4').onclick = function(){
    demo1.delete([ 2 ])
};

document.getElementById('demo1-test5').onclick = function(){
    demo1.setValue([ ])
};

</script>

取值

函数getValue(type), type类型 name, nameStr, value, valueStr

:::demo

<div id="demo2" class="xm-select-demo"></div>
<button class="btn" id="demo2-getValue">获取选中值</button>

<br/><br/>

<button class="btn" id="name">获取name数组</button>
<button class="btn" id="nameStr">获取name字符串</button>
<button class="btn" id="value">获取value数组</button>
<button class="btn" id="valueStr">获取value字符串</button>

<pre id="demo2-value"></pre>

<script>
var demo2 = xmSelect.render({
    el: '#demo2', 
    data: [
        {name: '张三', value: 1},
        {name: '李四', value: 2},
        {name: '王五', value: 3},
    ]
})

document.getElementById('demo2-getValue').onclick = function(){
    //获取当前多选选中的值
    var selectArr = demo2.getValue();
    document.getElementById('demo2-value').innerHTML = `\ndemo2.getValue()\n\n` + JSON.stringify(selectArr, null, 2);
}

var types = ['name', 'nameStr', 'value', 'valueStr'];
types.forEach(function(type){
    document.getElementById(type).onclick = function(){
        //获取当前多选选中的值
        var selectArr = demo2.getValue(type);
        document.getElementById('demo2-value').innerHTML = `\ndemo2.getValue('${type}')\n\n` + JSON.stringify(selectArr, null, 2);
    }
});


</script>
