如何从PHP打印按钮调用JavaScript函数

Question

What a weird question. If anyone has a better title for this, please go ahead and edit it; I can't think of what else to call it. I am printing a button from PHP using echo. The purpose of a button is to show a form by calling a JavaScript function that uses document.getElementById() to change the style attribute of the form tag to visible so the form is visible to the user. The problem I'm having is that the echoed string has to have quotes around it, the onclick event has to have quotes around it, and the parameter passed to the JavaScript function has to have quotes around it. I tried escpaing the quotes for the parameter with backslashes but that didn't work. Can anyone help me?

Here is my code:

echo "<input type = 'button' onclick = 'showform(\'psswdform\')' value = 'Change password'>";//this shows the form and needs quotes

JavaScript function:

function showform(id)
{
document.getElementById(id).style.visibility = "visible";
}

This works fine for me? (working example)

<?php

echo "<input type = 'button' onclick = 'showform(\"psswdform\")' value = 'Change password'>";//this shows the form and needs quotes

Generates:

<input type = 'button' onclick = 'showform("psswdform")' value = 'Change password'>
