Question

如果问题1是＆＃34; 1＆＃34;或问题2是＆＃34; 4＆＃34;我需要它显示绿色。当调用标记测验时，否则为红色。这个代码我哪里错了？ js位于外部文件中。

Html：

<body>
<table>
    <tr>
        <th>Questions</th>
        <th>Answer</th>
    </tr>
    <tr>
        <td id="1">
            Water is
            <ol>
                <li> Wet</li>
                <li> Ordinary</li>
                <li>Purify </li>
                <li> Water</li>
            </ol>
        </td>
        <td>
            <form name="question1" action="www.quizMarker.ca">
                <input type="text" name="quest1" placeholder="Enter Answer"> 
            </form>

        </td>
    </tr>
    <tr>
        <td id="2">
            Fire is
            <ol>
                <li> Wet</li>
                <li> Ordinary</li>
                <li>Purify </li>
                <li> Hot</li>
            </ol>
        </td>
        <td>
            <form name="question2" ction="www.quizMarker.ca">
                <input type="text" name="quest1" placeholder="Enter Answer"> 
            </form>

        </td>
    </tr>
</table>
<button type="button" onclick="markQuiz()">Mark Quiz</button>

js：

function markQuiz()
{
var q1 = document.forms['question1'];
var q1Ans = q1.elements['quest1'].value;

var q2 = document.forms['question2'];
var q2Ans = q2.elements['quest2'].value;

var row1 = document.getElementById("1");
var row2 = document.getElementById("2");

if(q1Ans = "1")
    {
        row1.style.backgroundColor = "green";
    }
else()
    {
        row1.style.backgroundColor = "red";
    }

if(q2Ans = "4")
    {
        row2.style.backgroundColor = "green";
    }
else()
    {
        row2.style.backgroundColor = "red";
    }
}

现在，当调用时，markQuiz没有做任何事情。此外，如果有更简单的方法来完成此任务，建议将有所帮助。

Answer 1

你可能需要＆＃34; ==＆＃34;或＆＃34; ===＆＃34;而不是＆＃34; =＆＃34;，这意味着分配。

 public ActionResult Index() { var x = objrepo.GetCountry();return View(x); }

Answer 2

代码中有一个额外的=符号

if(q1Ans = "1")
    {
        row1.style.backgroundColor = "green";
    }

正确的语法是：

if(q1Ans == "1")
        {
            row1.style.backgroundColor = "green";
        }

Answer 3

请检查我所做的更改

function markQuiz()
{
var q1Ans = document.forms['question1'].quest1.value;
var q1Ans = document.forms['question2'].quest2.value;

// PLease change the ids of the td ttag
var row1 = document.getElementById("table1");
var row2 = document.getElementById("table2");

if(q1Ans === "1")
    {
        row1.style.backgroundColor = "green";
    }
else
    {
        row1.style.backgroundColor = "red";
    }

if(q2Ans === "4")
    {
        row2.style.backgroundColor = "green";
    }
else
    {
        row2.style.backgroundColor = "red";
    }
}

尝试使用html，js和表单创建一个非常简单的测验
