通过参数将php变量传递给javascript函数PHP，JAVASCRIPT [英] Passing php variables through the parameters to a javascript function, PHP, JAVASCRIPT

问题描述

我正在尝试将字符串变量通过名为alertText的php函数的参数传递给名为alert的javascript函数，以将消息提示给屏幕，但是由于某种原因它不接受php变量，因此什么也没有被提醒到屏幕.请看一下:

I'm trying to pass a string variable through the parameter of a php function called alertText to a javascript function called alert, to alert a message to the screen, but it's not accepting the php variable for some reason, and nothing is being alerted to the screen. Please take a look:

testing.php

testing.php

function alertText($text) {

echo "

<script>
alert($text);
</script>

";

}

alertText("Hello");

?>

推荐答案

您需要单引号$ text变量，因为JavaScript无法将该变量识别为字符串.

You need to single-quote the $text variable, because JavaScript is not recognizing that variable as string.

<?php 
function alertText($text) {
    echo "<script>alert('$text');</script>";
}
alertText("Hello");
