See this sample snippet:

<html>
<head>
</head>
<body>
    <form name="frm">
        <input type="text" name="txt" value="Hello" />
        <input type="button" onclick="this.form.txt.readOnly = true;" value="Disable text field" /> 
        <input type="button" onclick="this.form.txt.readOnly = false;" value="Enable text field" />
        
        
        <input type="button" value="My Button" name="btn" /> 
        <input type="button" onclick="this.form.btn.disabled = true;" value="Disable button" /> 
        <input type="button" onclick="this.form.btn.disabled = false;" value="Enable button" />
        
        
        <select name="mySelect">
            <option value="india">India</option>
            <option value="america">America</option>
        </select>
        <input type="button" onclick="this.form.mySelect.disabled = true;" value="Disable drop down" />
