  回答 1 已采纳 I'm trying to create customizable checkboxes using buttons. I'm able to differentiate which button class has been selected, but I've been unable to track the button class post form submission. Ideally, instead of reseting the buttons to a default value when the page is loaded or submitted, I can keep whatever input was initially provided. I've tried using the isset() php function, but I don't think it's a valid solution in this circumstance. Are there any alternatives? Find my code below: <form id="my-form" method="post"> <html> <body > <style> .button { color: white; padding: 10px; text-align: center; text-decoration: none; display: inline-block; font-size: 12px; margin: 4px 2px; cursor: pointer; } .button1 { border-radius: 100%; background-color: green; border: none; } .button2 { border-radius: 100%; background-color: red; border: none; } </style> <div id="test1"></div> <div id="test2"></div> <!-- invalid code? <?php echo isset($_POST["t1test"]); echo isset($_POST["t2test"]); echo $_POST["t1test"]; echo $_POST["t2test"]; ?> --> <script type="text/javascript"> function makeButton(div, val) { var element = document.getElementById(val); var button = document.createElement("button"); var span = document.createElement("span"); // change to account for submitted settings if (element == null) { button.setAttribute("class", "button button1"); } else { var cL1 = element.classList.contains("button1"); var cL2 = element.classList.contains("button2"); element.parentNode.removeChild(element); if (cL2 == true) { button.setAttribute("class", "button button1"); } if (cL1 == true) { button.setAttribute("class", "button button2"); } } button.setAttribute("type", "button"); button.setAttribute("id", val); button.setAttribute("name", val); var testDiv = document.getElementById(div); testDiv.appendChild(button); button.addEventListener ("click", function() { makeButton(div, val); }) } window.onload = function() { makeButton("test1", "t1test"); makeButton("test2", "t2test"); } </script> </body> </html> <button id="submit">Submit</button> </form>
• 一个表单中的多个“链接”提交按钮 javascriptphpjquery

  回答 3 已采纳 I would like to create a form with multiple submit link buttons. I know it can be done by using and specifying the name of <button> or <input type="button"> something like this: In HTML: <form action="" method="get"> Other form elements here... <button type="submit" name="activated">Activated</button> <button type="submit" name="pending">Pending</button> <button type="submit" name="suspended">Suspended</button> </form> In PHP: <?php if(isset($_GET["activated"])) { Activated codes here... } elseif(isset($_GET["pending"])) { Pending codes here... } elseif(isset($_GET["suspended"])) { Suspended codes here... } ?> I want the submit buttons to be done by using link, not <button> or <input type="submit"> something like this: <a href="#">Activated</a> <a href="#">Pending</a> <a href="#">Suspended</a> I heard that it can be done by using JavaScript or JQuery but I don't know how, anyone knows? Update: What I want to happen is when I clicked the "Activated" link for example, I want only to process the logic under isset($_GET["activated"]). The reason behind: The reason why I want to have a submit link buttons instead of normal submit button tags is that, I want to use this bootstrap dropdown button style to change the status of user(s) on table: and it is based on links, so that's why. PS: Sorry for bad English, not my native language.
