警報（模態窗口）框聲明

Question

當用PHP編寫的語句生效時，我將如何彈出警報框？

我現在要做的JS代碼是這樣的：

$(".bAlert").click( function() {
    jAlert('This is a custom alert box. Title and this text can be easily editted', 'Alert Dialog Sample');
});

將此代碼用於按鈕時，該代碼可以正常工作，但我希望在該語句生效時顯示它：

if ($operation == "divide") { 
    $answer = $number1 / $number2;
    $operation = "÷";
} else {
    $output = "CODE TO MAKE THIS WORK HAS TO GO HERE"; 
}

使用按鈕的方式如下：

<input type="button" value="Usual alert" class="basicBtn mr10 ml10 bAlert" />

Answer 1

只需將其放在else語句中

if ($operation == "divide"):
    $answer = $number1 / $number2;
    $operation = "÷";
 else:
    echo "<script>jAlert('This is a custom alert box. Title and this text can be easily editted', 'Alert Dialog Sample');</script>"; 
    endif;
