我已经在网上搜索过，但是找不到一种方法来用空格（“”）分割char数组并将每个单词存储到一个向量中。

$(document).ready(function() {
  this.json = {
    "Students": [{
        "id": "1","hometown": "London","gender": "Male","GPA": "8","name": "Lee",},{
        "id": "2","hometown": "NY","GPA": "9","name": "Shaldon",{
        "id": "3","hometown": "Paris","gender": "Female","GPA": "7","name": "Julie",}
    ]
  };
  
  this.renderTable = function(Students) {
    var tbody = document.getElementById('tbody');
    tbody.innerHTML = "";
    for (var i = 0; i < Students.length; i++) {
      var tr = "<tr>";
      tr += "<td>ID</td>" + "<td>" + Students[i].id + "</td></tr>";
      tr += "<td>HomeTown</td>" + "<td>" + Students[i].hometown + "</td></tr>";
      tr += "<td>Gender</td>" + "<td>" + Students[i].gender + "</td></tr>";
      tr += "<td>GPA</td>" + "<td>" + Students[i].GPA + "</td></tr>";
      tr += "<td>NAME</td>" + "<td>" + Students[i].name + "</td></tr>";
      tr += "<hr>";
      tbody.innerHTML += tr;
    }
  }

  this.renderTable(this.json.Students);

  console.log(this.json.Students);
  //code for filtering//
  this.Filter = function() {
    var search = document.getElementById('search');
    var category = document.getElementById('category');
    var filteredObj = this.json.Students;
    filteredObj = $.map(this.json.Students,function(val,key) {
      if (search.value === val[category.value]) return val;
    });
    filteredObj.length>0 ? this.renderTable(filteredObj) : this.renderTable(this.json.Students);
  }

});
