下拉并确认问题 [英] Drop Down and confirm problems

问题描述

你好，

我目前正在构建一些表格，并且需要你们的帮助，因为我不知道该怎么做；/.

所以:

1.我尝试过使用确认对话框.我正在使用jformer，这是一个很好的表单框架，尽管文档缺少信息.该表单是使用类和函数完全构建的.

提交时具有以下功能.

Hi there,

I''m currently building some forms and would require some help from you guys as I don''t know what to do more ;/.

So:

1. I''ve tried working with the confirm dialogue box. I am using jformer, a form framework which is quite nice though documentation is lacking information. The form is completely built using classes and functions.

There is the following function on submission.

function onSubmit($formValues) 
{
$formValues = $formValues->registrationPage->registrationSection1;
							
							$studentID = $formValues->studentid;

etc...
}

有没有一种方法可以在提交时按确认插入javascript?这样我就可以进行确认对话，并根据用户按下的是(是/否)，我有一个if语句执行应做的事情(即，在我的情况下，提交数据/删除)

2. jformer框架中的触发器.

我想单击一个下拉列表，它显示另一个下拉列表.我尝试了以下操作，但是仅通过使用复选框，我不知道如何使用下拉菜单进行操作:

Is there a way to insert a javascript confirm on submition is pressed? So that I have a confirmation dialogue and according to which the user pressed (Yes / No) I have an if statement doing what is supposed to do (ie the submission of data / deletion in my case)

2. Triggers in the jformer framework.

I would like to have a drop down list which on click, it shows another drop down list. I have tried the following but only with the use of a checkbox, I have no clue on how to do it with a drop down:

new JFormComponentMultipleChoice('selectGroup2', '', array(
        						array('value' => 'secondGrp', 'label' => 'Student has second group?'),
            					),
           						array()),
								
     new JFormComponentDropDown('group2', 'Group 2:', $groups2array,
								array(
										'validationOptions' => array('required'),
										'dependencyOptions' => array(
										'dependentOn' => 'selectGroup2',
										'display' => 'hide',
										'jsFunction' => '$("#selectGroup2-choice1").is(":checked");'
										),
							)),	

从上面可以看到，该函数检查该复选框是否已选中，如果未选中，则隐藏.

我需要一个下拉列表，而不是一个复选框.第一个下拉菜单显示新的下拉菜单，该下拉菜单根据用户选择的内容显示数据.

我已经发现如何使用以下方法从数据库中填充下拉列表:

As you can see from the above, the function checks if the checkbox is checked and is hidden if not checked.

I need a dropdown instead of a checkbox. The first dropdown displays the new drop down showing data according to what the user selected.

I allready found out how to populate the drop down from the database by using the following:

$query = "SELECT * FROM course";

$resultset = $db->query($query);

$coursearray = array();

array_push($coursearray, array ('value' => '','label' => ' - Select an Option - ','selected' => true));	

while ($row = mysql_fetch_array($resultset))
	{	
		array_push($coursearray, array ('value' => $row["course_ID"], 'label' => $row["course_Name"],));  
	}

填充数组后，我使用以下命令填充下拉列表:

after the array is populated, I use the following to populate the dropdown:

new JFormComponentDropDown('course', 'Course:', $coursearray,
							array(							
								'validationOptions' => array('required')
							),
							array(
								'tip' => '<p>Select Course</p>',
							)),

我知道我提出的要求要多一些，但是我几乎尝试了所有可能的事情，并花了几天的时间研究某些东西的工作原理.非常感谢您的帮助，我将捐出一些小钱给谁来帮助我找到解决方案！

谢谢，
Francesco

I know I am asking a bit more then I should but I tried almost everything I could and spent days of research on how certain stuff works. Your help is much appreciated and I would donate something small to whom helps me find a solution to these!
