how to add values one by one in an array

我想在一个数组中添加8个单击按钮的值。
当用户按下任何按钮时,存储在数组中的该按钮的ID/值,但我的数组只在数组[0]中保存第一个值。
如何在数组中插入其他值?
代码如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 | function reply_click(obj) { var id = [obj.id]; for (i = 0; i <= id; i++) { alert(id); } } var arr = [id]; alert(arr); if (id[0] =="1") { alert(6666666666); } if (id[0] =="2") { id[0] = 1; id[1] = 2; alert(777777777777); } if (id[0] =="3") { id[0] = 1; id[1] = 2; id[2] = 3; alert('login'); } alert(id); $(document).on('click', '.btn', function() { alert($(this).val()); var myvalues = $(this).val(); alert(myvalues); var cars = [myvalues,"myvaluesv","Toyota"]; alert(cars); var x = cars.length; alert(x); }); |
1 2 3 4 5 6 7 8 9 10 11 | <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"> <button id="1" onClick="reply_click(this)">1</button> <button id="2" onClick="reply_click(this)">2</button> <button id="3" onClick="reply_click(this)">3</button> <button id="tahira" name="btn" class="btn" value="tahirahassan">hi tahira</button> <button id="sobia" name="btn" class="btn" value="sobia">hi sobia</button> <form action="testingjquery.php" method="post"> <input type="submit" id="btn1" class="btn111" name="val1" value=" i am tahira" /> <input type="submit" id="btn2" class="btn112" name="val1" value="hassan" /> </form> |
你可以试试这个
