如果else if语句在mousedown事件 [英] if else if statement on mousedown event
问题描述
我的目标是为每个点击的项目出现一个不同的对话框。我目前有一个设置，并认为我可以添加一个if语句。如果mouseown在div_a，dialog_a，否则如果mousedown在div_b，dialog_b等...我是新的编码，不能这个数字。
My goal is to have a different dialog box appear for each item clicked. I currently have one setup and figured I can just add an if statement. If mousedown on div_a, dialog_a, else if mousedown on div_b, dialog_b, etc... I am new to coding and cant figure this one out.
这是我的代码对于对话框：
Here is my code for the dialog:
$(document).ready(function(){
$("#questiona").mousedown(function(){
$("#dialoga").dialog();
});
});
推荐答案
由于你是新的编码，我建议使用jQuery团队的jQueryUI库 - 其中包含一个 .dialog（）功能（他们称之为小部件）。以下是它的工作原理：
Since you are new to coding, I suggest using the jQuery team's jQueryUI library -- which includes a .dialog() capability (they call it a "widget"). Here's how it works:
（1）在您的<$ c $中包含jQuery 和 jQueryUI库c>< head>< / head> 标签。请注意，您还必须为jQueryUI添加适当的CSS主题库（或对话框将不可见）：
(1) Include both jQuery and the jQueryUI libraries in your <head></head> tags. Note that you must also include an appropriate CSS theme library for jQueryUI (or the dialogs will be invisible):
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/themes/flick/jquery-ui.css" />
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
（2）在HTML中创建一个空的div，并初始化作为一个对话框：
(2) Create an empty div in your HTML, and initialize it as a dialog:
HTML：
<div id="myDlg"></div>
jquery：
$('#myDlg').dialog({
autoOpen:false,
modal:true,
width: 500,
height: 'auto'
});
（3）然后，当您准备好显示对话框时，在打开对话框之前，将新数据插入到 myDlg div中：
(3) Then, when you are ready to display the dialog, insert new data into the myDlg div just before opening the dialog:
$('#myDlg').html('<div>This will display in the dialog</div>');
$('#myDlg').dialog('open');
上述允许您更改对话框的内容，并每次使用重复的对话DIV
The above allows you to change the content of the dialog and use the re-same dialog DIV each time.
这是工作示例的样子：
HTML：
<div id="myDlg"></div>
<div id="questiona" class="allques">
<div class="question">What is 2 + 2?</div>
<div class="answer">4</div>
</div>
<div id="questionb" class="allques">
<div class="question">What is the 12th Imam?</div>
<div class="answer">The totally wacky reason why Iran wants a nuclear bomb.</div>
</div>
jQuery：
var que,ans;
$('#myDlg').dialog({
autoOpen:false,
modal:true,
width: 500,
height: 'auto',
buttons: {
"See Answer": function(){
$('#myDlg').html(ans);
$('.ui-dialog-buttonset').next('button').hide();
},
"Close": function(){
$('#myDlg').html('').dialog('close');
}
}
});
$('.allques').click(function(){
que = $(this).find('.question').html();
ans = $(this).find('.answer').html();
$('#myDlg').html(que).dialog('open');
});
