JS makes a global search on the front-end page

This time I will bring you JS to make a global search on the front-end page. What are the precautions for using JS to make a global search on the front-end page? The following is a practical case, let's take a look.

The rendering is as follows:

<input type="text" id="campus" class="layui-input" onkeyup="ck(this.value);" placeholder="请输入要查找的英语屋">//输入触发框 
<p class="layui-input-block layui-form" id="cam" lay-filter="cam">这个是要显示的校区的容器，渲染的就是这个页面</p>

//模板数据 
//因为这块用到了layui的语句和jfinal的语句，所以需要把layui的#用jfinal的#让layui当作普通字符串输出 
<script type="text/html" id="searchText"> 
    #for(x : CampusKit.findListByAccount(loginAccount))//jfinal的语句，循环 
    //这里把原来选择的数据显示出来，已经选择的数据，显示，如果不显示，保存的话，会把这些数据默认成没有选择的 
    #if(sysAccountCampusIds.contains(x.id.toString())) 
      <input type=&#39;checkbox&#39; value="#(x.id)" name=&#39;campus&#39;  
        #(sysAccountCampusIds.contains(x.id.toString()) ? &#39;checked="checked"&#39;:&#39;&#39;) 
        title="#(x.campusName)" id=&#39;campusBox#(x.id)&#39;> 
    #end   
//这里用到了layui的语句和jfinal的语句结合，#(x.campusName) jfinal 的语句，{{#("#") if(isContains("#(x.campusName)",d.val)){ }}中的d.val因为if用的是layui的语句，所以直接写就可以，一般都是{{d.val}}这样写 
    {{#("#") if(isContains("#(x.campusName)",d.val)){ }} 
        <input type=&#39;checkbox&#39; value="#(x.id)" name=&#39;campus&#39;  
        #(sysAccountCampusIds.contains(x.id.toString()) ? &#39;checked="checked"&#39;:&#39;&#39;) 
        title="#(x.campusName)" id=&#39;campusBox#(x.id)&#39;> 
    {{#("#") } }} 
    #end 
</script> 
//str字符串是否包含substr字符串 
function isContains(str, substr) { 
  return str.indexOf(substr) >= 0; 
} 
//layui模板的写法 
var getTpl = searchText.innerHTML;//写到js方法外边这样只加载一次，不用每次都加载，速度快 
/* 前端页面的搜索 */ 
 function ck(campusName){ 
  //渲染模版 
  layui.laytpl(getTpl).render({"val":campusName}, //json值 
      function(html){ 
    $("#cam").html(html);//jquery把模板加载到p  id是cam中<p id="cam"></p> 
    console.log(html); 
    layui.form.render(null,"cam"); //更新这个容器中的页面 
  }); 
}
