Help with syntax please

bgbs

I have this input box wrapped in php code. (I've only pasted the portion of that php code.)

<?php
case 'email':
			$html .= '
	<input  name="s" id="s" value="Email..." type="text" size="18" value="'.esc_html($var['default']).'" name="'.esc_attr($opt).'" id="'.esc_attr($opt).'" class="mc_input"/>';
	break;
?>

And I would like to add this javascript into the input form

onfocus="if (this.value == 'Search...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search...';}

So, the newb that I am, I tried this and got a syntax error

<input  name="s" id="s"  onfocus="'.if (this.value == 'Search...') {this.value = '';}.'" onblur="'.if (this.value == '') {this.value = 'Search...';}.'" value="Email..." type="text" size="18" value="'.esc_html($var['default']).'" name="'.esc_attr($opt).'" id="'.esc_attr($opt).'" class="mc_input"/>';

Any ideas how to properly integrate this javascript code into PHP?

Thanks in advance

Since in the PHP code you are wrapping the string in single quotes, any literal single quotes that you want to appear within that string must be escaped with a back-slash, e.g.:

$html = 'foo="this here\'s a test, y\'all."';

I'm a total newb
Can you be more specific how I can do this with javascript?
I tried figuring out your example and cooked something like this, but it still errors

<input    $html = 'onfocus="\if (this.value == 'Search...') {this.value = '';}\"'   name="s" id="s" value="Email..." type="text" size="18" value="'.esc_html($var['default']).'" name="'.esc_attr($opt).'" id="'.esc_attr($opt).'" class="mc_input"/>';

I'd like to add that onfocus and onblur should be inside the input tags

<?php
case 'email':
            $html .= '
    <input  name="s" id="s" value="Email..." type="text" size="18" value="'.esc_html($var['default']).'" name="'.
esc_attr($opt).'" id="'.esc_attr($opt).'" class="mc_input" 
onfocus="if (this.value == \'Search...\') {this.value = '';}" onblur="if (this.value == '') {this.value = \'Search...\';}" />';
    break;
?>
