How do I use an image as a submit button?

问题:

Can someone help to change this to incorporate an image called BUTTON1.JPG instead of the standard submit button?

<form id='formName' name='formName' onsubmit='redirect();return false;'>
    <div class="style7">
        <input type='text' id='userInput' name='userInput' value=''>
        <input type='submit' name='submit' value='Submit'>
    </div>
</form> 

回答1:

Use an image type input:

<input type="image" src="/Button1.jpg" border="0" alt="Submit" />

---

The full HTML:

<form id='formName' name='formName' onsubmit='redirect();return false;'>
  <div class="style7">
    <input type='text' id='userInput' name='userInput' value=''>
    <input type="image" name="submit" src="https://jekyllcodex.org/uploads/grumpycat.jpg" border="0" alt="Submit" style="width: 50px;" />
  </div>
</form>

Why not:

<button type="submit">
<img src="mybutton.jpg" />
</button>

回答3:

Use CSS :

input[type=submit] {

background:url("BUTTON1.jpg");

}

For HTML :

<input type="submit" value="Login" style="background:url("BUTTON1.jpg");">

Just remove the border and add a background image in css

Example:

$("#form").on('submit', function() {
   alert($("#submit-icon").val());
});

#submit-icon {
  background-image: url("https://pixabay.com/static/uploads/photo/2016/10/18/21/22/california-1751455__340.jpg"); /* Change url to wanted image */
  background-size: cover;
  border: none;
  width: 32px;
  height: 32px;
  cursor: pointer;
  color: transparent;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="form">
  <input type="submit" id="submit-icon" value="test">
</form>

</div>
</form>
