为什么在键入单词以搜索CSV中的数据时，搜索框会变得滞后？ [英] Why searchbox become lagging when typing word to search data in CSV?

问题描述

我使用开放的街道地图和传单开发了商店定位器。问题是，当我想输入搜索框时，它将变得滞后以完成这个词。该商店定位器从具有300 ++数据的CSV文件中读取。以下是搜索框的代码：

I developed the store locator using open street map and leaflet. The problem is when I want to type in searchbox it will become lagging to finish the word. That store locator read from the CSV file that has 300++ data. Below is the code for the searchbox:

var locationLat = [];
var locationLng = [];
var locMarker;
var infoDiv = document.getElementById('storeinfo');
var infoDivInner = document.getElementById('infoDivInner');
var toggleSearch = document.getElementById('searchIcon');
var hasCircle = 0;
var circle = [];
//close store infor when x is clicked
var userLocation;
$("#infoClose").click(function() {
  $("#storeinfo").hide();
  if (map.hasLayer(circle)) {
    map.removeLayer(circle);
  }
});
var listings = document.getElementById('listingDiv');
var stores = L.geoJson().addTo(map);
var storesData = omnivore.csv('assets/data/table_1.csv
function setActive(el) {
  var siblings = listings.getElementsByTagName('div');
  for (var i = 0; i < siblings.length; i++) {
    siblings[i].className = siblings[i].className
      .replace(/active/, '').replace(/\s\s*$/, '');
  }
  el.className += ' active';
}

function sortGeojson(a,b,prop) {
  return (a.properties.name.toUpperCase() < b.properties.name.toUpperCase()) ? -1 : ((a.properties.name.toUpperCase() > b.properties.name.toUpperCase()) ? 1 : 0);
}

storesData.on('readyunction() {

  var storesSorted = storesData.toGeoJSON();
  //console.log(storesSorted);
  var sorted = (storesSorted.features).sort(sortGeojson)
  //console.log(sorted);
  storesSorted.features = sorted;
  //console.log(storesSorted)
  stores.addData(storesSorted);

  map.fitBounds(stores.getBounds());
  toggleSearch.onclick = function() {
    //var s = document.getElementById('searchbox');
    //if (s.style.display != 'none') {
      //s.style.display = 'yes';
      //toggleSearch.innerHTML = '';
      //$("#search-input").val("");

      //search.collapse();
      //document.getElementById('storeinfo').style.display = 'none';
      //$('.item').show();
    //} else {
      //toggleSearch.innerHTML = '';
      //s.style.display = 'block';

      //attempt to autofocus search input field when opened
      //$('#search-input').focus();
    //}
  };
  stores.eachLayer(function(layer) {

    //New jquery search
    $('#searchbox').on('change paste keyup', function() {
      var txt = $('#search-input').val();
      $('.item').each(function() {
        if ($(this).text().toUpperCase().indexOf(txt.toUpperCase()) != -1) {
          $(this).show();
        } else {
          $(this).hide();
        }
      });
    });

有没有解决这个问题的方法？我一直在寻找解决方案来解决这个问题，但仍然无法找到解决方案。谢谢



我尝试过的方法：



我试过学习使用bootstrap搜索表，但我确实知道如何申请这个商店定位器。

Is there any way to solve this problem? I've been searching solution to solve this but still cannot find the solution. Thank you

What I have tried:

I tried learn to use bootstrap search table but i did know how to apply in this store locator.

推荐答案

（＃infoClose）。click（function（）{

("#infoClose").click(function() {

（＃storeinfo）。hide（）;
if（map.hasLayer（ circle））{
map.removeLayer（circle）;
}
}）;
var listings = document.getElementById（'listingDiv'）;
var stores = L.geoJson（）。addTo（map）;
var storesData = omnivore.csv（'assets / data / table_1.csv
function setActive（el）{
var siblings = listings.getElementsByTagName（'div'）;
for （var i = 0; i< siblings.length; i ++）{
siblings [i] .className = siblings [i] .className
.replace（/ active /，''）。replace（ / \\\ *

("#storeinfo").hide(); if (map.hasLayer(circle)) { map.removeLayer(circle); } }); var listings = document.getElementById('listingDiv'); var stores = L.geoJson().addTo(map); var storesData = omnivore.csv('assets/data/table_1.csv function setActive(el) { var siblings = listings.getElementsByTagName('div'); for (var i = 0; i < siblings.length; i++) { siblings[i].className = siblings[i].className .replace(/active/, '').replace(/\s\s*

/，''）;
}
el.className + ='active';
}

函数sortGeojson（a，b，prop）{
return（a.properties.name.toUpperCase（）< b.properties.name.toUpperCase（））？ - 答:(（a .properties.name.toUpperCase（）> b.properties.name.toUpperCase（））？1：0）;
}

storesData.on（'readyunction（）{

var storesSorted = storesData.toGeoJSON（）;
//console.log(storesSorted）;
var sorted =（storesSorted.features）.sort（sortGeojson）
/ /console.log(sorted）;
storesSorted.features = sorted;
//console.log(storesSorted）
stores.addData（storesSorted）;

map.fitBounds（stores.getBounds（））;
toggleSearch.onclick = function（）{
// var s = document.getElementById（'searchbox'）;
// if（s.style.display！='none'）{
//s.style.display ='yes';
//toggleSearch.innerHTML =' ';
//

/, ''); } el.className += ' active'; } function sortGeojson(a,b,prop) { return (a.properties.name.toUpperCase() < b.properties.name.toUpperCase()) ? -1 : ((a.properties.name.toUpperCase() > b.properties.name.toUpperCase()) ? 1 : 0); } storesData.on('readyunction() { var storesSorted = storesData.toGeoJSON(); //console.log(storesSorted); var sorted = (storesSorted.features).sort(sortGeojson) //console.log(sorted); storesSorted.features = sorted; //console.log(storesSorted) stores.addData(storesSorted); map.fitBounds(stores.getBounds()); toggleSearch.onclick = function() { //var s = document.getElementById('searchbox'); //if (s.style.display != 'none') { //s.style.display = 'yes'; //toggleSearch.innerHTML = ''; //
