為什么這個javascript不會運行?

[英]Why wont this javascript run?

有人為我創建了這個代碼: http//jsfiddle.net/kzFWa/

var downloadButton = document.getElementById("continue");
var counter = 60;
var newElement = document.createElement("p");
newElement.innerHTML = "<h3>or click here to continue in 60 seconds</h3>";
var id;

downloadButton.parentNode.replaceChild(newElement, downloadButton);

id = setInterval(function() {
    counter--;
    if(counter < 0) {
        newElement.parentNode.replaceChild(downloadButton, newElement);
        //newElement.innerHTML = "<a href="survey.php">Click Me To Continue</a>"
        clearInterval(id);
    } else {
        newElement.innerHTML = "<h3>or click here to continue in  " + counter.toString() + " seconds.</h3>";
    }
}, 1000);

但是,如果我改變了

newElement.parentNode.replaceChild(downloadButton, newElement); 

newElement.innerHTML = "<a href="survey.php">Click Me To Continue</a>"

代碼將不再運行。 我究竟做錯了什么?

您在語法錯誤:

newElement.innerHTML = "<a href="survey.php">Click Me To Continue</a>"

雙引號不能在雙引號字符串中使用。 轉義或更改為單引號和雙引號的組合:

newElement.innerHTML = '<a href="survey.php">Click Me To Continue</a>';

您在語法錯誤:

newElement.innerHTML = "<a href="survey.php">Click Me To Continue</a>"

檢查控制台,你會看到:

SyntaxError:missing; 在聲明之前newElement.innerHTML =“點擊我繼續”

所以代碼沒有很好地形成,改變它:

newElement.innerHTML = "<a href='survey.php'>Click Me To Continue</a>";
