javascript - Deal with big DataList -
https://jsfiddle.net/pb47ap8t/2/
var fruits = ["test"]; (var i=0;i<500;i++){ fruits.push("test"); } // var datalist = document.getelementbyid('datalist'); var frag = document.createdocumentfragment(); (var in fruits) { if (fruits.hasownproperty(i)) { var option = document.createelement("option"); option.textcontent = fruits[i]; option.value = fruits[i]; frag.appendchild(option); } } datalist.appendchild(frag);
i want populate datalist (arround 500 values), how can without issues concerning massive data loading ?
apologies writing answer , not commenting don't have enough reputation. freezes because of populating drop down on clicking element when data fetched server. loading asynchronously help..
