性能测试
数据渲染耗时测试
事实证明分页是好使的 ^_^
html
<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>
