<select> tag and returning multiple values to javascript method

由 人走茶凉 提交于 2021-02-19 04:29:05
问题 I have an issue with the data which is sent from a drop down menu, the selector only returns a single value, even when multiple values are selected. I have searched online for a solution to this, but they all use PHP, JQuery or some method outside the scope of the course I am taking; to capture multiple selected items. I have tried .value of the individual options, but that returns all of the options rather than just the ones which are selected. Is there some kind of trick to sending multiple

Cookie multiple values

问题 In the php manual under section "cookies" it states that you can add multiple values to a single cookie by simply adding a '[]' to the cookie name. At first my understanding of this was to do the following: <?php setcookie("[user1]", "bill"); setcookie("[user2]", "tom"); print_r($_COOKIE); ?> and the out put was: 'Array ( )' Obviously after seeing an empty array I knew something was not right but, I had followed what the manual had stated. So I went in developer mode in the browser to see all

Hashtable with multiple values for single key

由 江枫思渺然 提交于 2019-12-09 08:56:06
问题 I want to store multiple values in single key like: HashTable obj = new HashTable(); obj.Add("1", "test"); obj.Add("1", "Test1"); Right now this throws an error. 回答1: you can put your test,test1,test2,... in a table and then put this table in a Hashtable as a value for the key which will be the same for all them. For example try something like this: List<string> list = new List<string>(); list.Add("test"); list.Add("test1"); and then: HashTable obj = new HashTable(); obj.Add("1", list); 回答2:

问题 I have a table with checkboxes that the user can check and delete that row in the table. I have everything working, but if the user checks two boxes, it only retrieves the first one on the table. <tr> <td><input type="checkbox" name="id" value="${user.id}" /></td> <td><c:out value="${user.name}" /></td> <td><c:out value="${user.email}" /></td> </tr> This is just an example of my HTML. Here is part of my servlet. String id = request.getParameter("id"); So, again, I can get the first value

How to assign multiple values at once to multi-dimensional array AFTER creating it - in C?

由 ﹥＞﹥吖頭↗ 提交于 2019-12-06 09:44:11
I'm programming in C and wonder if it's possible to assign multiple values at once to a multi-dimensional array? I have tried some technique but all have failed! I’m NOT interested to loop through the array to assign values (I want the fasted way to assign new values to all index in the array). The array I’m working with: ary[4][4].

You can initialize it and you can assign individual members via indexing. 6.3.2.1 A modifiable lvalue is an lvalue that does not have array type, does not have ... And a
