Question

所以目前我的应用程序使用document.write向用户提供搜索结果，但我希望将结果输出到<div class="main">中的表中，但我不会希望只有在表格给出结果时才能在开头看到表格，怎么办呢？提前感谢您的帮助！：）

Answer 1

默认情况下在表格中设置display:none，并在找到结果时将其设置为display:block。您可以在元素上设置diplay:none内联，并使用if语句中的javascript更改它if(matches > 0)

Answer 2

在您的功能＆＃34;搜索（）＆＃34;中，就在您的＆＃34; for＆＃34;之前循环，声明一个变量＆＃34; searchResult＆＃34;，然后连接此变量中的每个结果行。最后，将结果放在＆＃34; main＆＃34; div：

    function search() {
var brandCheck=checkBrand();
 var networkCheck=checkNetwork();
var model
model = document.getElementById("phone_model"); //???
var f
f = document.getElementById("internet"); //checkbox
var g
g = document.getElementById("upcost");  //auto
var h
h = document.getElementById("month_cost"); //auto ask
var i
i = document.getElementById("contract_length"); //dropdown
// Declare your searchResult variable        
var searchResult = "";
        for (var p=0;p<contract.length;p++) {
        var matches = 0;
var total_number_of_conditions = 10;

if (brandCheck == contract[p].brand) matches += 1;
if (model.value == contract[p].model) matches += 1;
if (networkCheck == contract[p].network) matches += 1;
if (minutes >= contract[p].minutes) matches += 1;
if (text >= contract[p].texts) matches += 1;
if (f.value == contract[p].data) matches += 1;
if (g.value == contract[p].upcost) matches += 1;
if (h.value == contract[p].monthlycost) matches += 1;
if (i.value == contract[p].length) matches += 1;
    if (matches > 0) {
        var percentage_matched = 100 * (matches / total_number_of_conditions);
// Concatene lines of the table result
        searchResult += "<tr><td>" + contract[p].brand + 
            "</td><td>" + contract[p].model + 
            "</td><td>" + contract[p].network + 
            "</td><td>" + contract[p].minutes + 
            "</td><td>" + contract[p].texts + 
            "</td><td>" + contract[p].data + 
            "</td><td>" + contract[p].upcost + 
            "</td><td>" + contract[p].monthlycost + 
            "</td><td>" + contract[p].length + 
            "</td><td>" + percentage_matched + "%</td></tr>";   
    }
        }
// Check if there is result
    if(searchResult != ""){
        searchResult = "<table>" + searchResult + "</table>";
    }
// Put the result in the main div
    document.getElementsByClassName('main')[0].innerHTML = searchResult;
            }

将搜索结果放入表js
