语法错误：预期的表达式，得到 ''

Question

I know there are many questions with this same title, but all I've seen do not apply to my problem.

I currently have a PHP function that looks like this:

function mostraFraseStatus($i, $f){
        print'document.getElementById("cliente'.$i.'").innerHTML = "<span style=\'color:#FF0000\'>'.$f.'</span>";';
    }

Within the validations, it is executed this way:

} else {
                        mostraFraseStatus($idProdutoSelecionado, "Text Here");
                    }

It works normally, but I need to change that print to an alert . I have tried the following:

function mostraFraseStatus($i, $f){
        echo "<script type='text/javascript'>alert('Test');</script>";
    }

However I am getting the title error while executing the function by the navigator: SyntaxError: expected expression, got '<'

How can I fix it?

Answer 1

The error is most likely caused by echo 'ing a <script> block inside an existing <script> block. Simply change your code like so:

function mostraFraseStatus($i, $f){
    echo "alert('Test');";
}
