数据渲染耗时测试​

事实证明分页是好使的 ^_^

<div id="demo1" class="xm-select-demo"></div>
<button class="btn" id="demo1-test1">测试1000条</button>
<button class="btn" id="demo1-test2">测试10000条</button>
<button class="btn" id="demo1-test3">测试10000条+分页</button>
<pre id="demo1-result"></pre>

<script>
function run(count, paging){
    //生成数据
    var data = [];
    for(var i = 0; i < count; i++){
        data.push({
            name: '测试数据' + i,
            value: i,
        })
    }
    
    //记录开始渲染时间
    var startTime = Date.now();
    
    var demo1 = xmSelect.render({
        el: '#demo1', 
        paging,
        data
    })
    
    //记录结束时间
    var endTime = Date.now();
    
    document.getElementById('demo1-result').innerText = `渲染耗时: ${endTime - startTime} ms`
}

document.getElementById('demo1-test1').onclick = function(){
    run(1000, false)
};

document.getElementById('demo1-test2').onclick = function(){
    run(10000, false)
};

document.getElementById('demo1-test3').onclick = function(){
    run(10000, true)
};

run(1000, false);

</script>
