如何在计算某个结果后显示建议？

在用户计算输入结果后，如何显示推荐列表等内容？例如，让用户输入家庭工资并计算PCI（人均收入），然后键入并按下计算按钮，然后根据家庭所拥有的PCI数量触发推荐列表（？也许表显示根据不同类别的PCI不同的结果）如何在计算某个结果后显示建议？

<!DOCTYPE html> 
<html> 

<head> 
<script src="common.js"></script> 
<script> 
    function cal() 
    { 
     var salary1 = document.getElementById('salary1').value; 
     var salary2 = document.getElementById('salary2').value; 
     var salary3 = document.getElementById('salary3').value; 
     var salary4 = document.getElementById('salary4').value; 
     var members = document.getElementById('members').value; 


     var total = (parseInt(salary1) + parseInt(salary2) + parseInt(salary3) + parseInt(salary4))/parseInt(members); 
     document.getElementById('total').value = total; 

     alert (total); 
    } 

</script> 
</head> 

<body> 
<h1>Want to know which bursary your eligible?</h1> 
<input id="salary1" value="" placeholder="Enter your 1st family income..."/>

<button onclick="cal()"> Calculate PCI!</button>

您可以创建一个隐藏的div保存数据则显示，DIV，当用户点击该按钮

HTML：

<div id="divToShow" style="display:none;" class="table_list" > 
    //put your data table here 
    </div> 

    <input type="button" name="myButton" value="Show Div" onclick="showDiv()" />

Java脚本：

function showDiv() { 
    document.getElementById('divToShow').style.display = "block"; 
}

这应该让你在那里：Jsfiddle。

<form id="form"> 
    <input id="number1" type="number" min="1" name="number" placholder="add value one"> + 
    <input id="number2" type="number" min="1" name="number" placholder="add value one"> 
    <button>Submit</button> 
</form>

var form = document.getElementById('form'); 
    number1 = document.getElementById('number1'); 
    number2 = document.getElementById('number2'); 
form.onsubmit = function() { 
    var total = +number1.value + +number2.value; // add + before 
    alert(total); 
};
