问题描述
我使用jquery可拖动的插件在我的asp.net MVC 3应用程序,在这里用户可以拖动/删除表中的一行。
I am using jquery draggable plugin in my asp.net MVC 3 app, where user can drag/drop a row of a table.
我的要求是,我需要标记表作为非可拖动和/或非投掷的一些行(以便其他行不能被丢弃到它们)。
My requirement is that I need to mark some rows of table as non-draggable and/or non-droppable (so other rows can’t be dropped onto them).
有人能指导我如何启用此?

我把它真的pretty在小提琴
HTML
I made it really pretty in the fiddle HTML
Note: Row 4 is disabled
<h1>Table 1</h1>
<table id="Table1">
<tr><td>Row 1</td></tr>
<tr><td>Row 2</td></tr>
<tr><td>Row 3</td></tr>
<tr class='disabled'><td>Row 4</td></tr>
<tr><td>Row 5</td></tr>
</table>
<h2>Table 2</h2>
<table id="Table2">
<tr><td>Row 6</td></tr>
<tr><td>Row 7</td></tr>
<tr><td>Row 8</td></tr>
<tr><td>Row 9</td></tr>
<tr><td>Row 10</td></tr>
</table>
和JQuery(需要包括jQuery UI的lib和CSS以及)
and JQuery (needs to include jquery ui lib and css as well)
$("#Table1 tr:not(.disabled), #Table2 tr:not(.disabled)").draggable({
helper: 'clone',
revert: 'invalid',
start: function (event, ui) {
$(this).css('opacity', '.5');
},
stop: function (event, ui) {
$(this).css('opacity', '1');
}
});
$("#Table1, #Table2").droppable({
drop: function (event, ui) {
$(ui.draggable).appendTo(this);
alert($(ui.draggable).text());
//fire ajax here if needed
}
});
和一些CSS
table{ width:200px; border: brown 1px solid; padding:5px;}
table tr {background-color:#FCF6CF;}
table tr:hover:not(.disabled) {background-color:#ECF1EF;}
tr:not(.disabled){cursor:pointer;}
tr.disabled{background-color:#FEE0C6; cursor:not-allowed;}
MVC3相关栏目
要做到这样的事情在MVC3,你会从你的视图模型的项目填充使用foreach循环表,即
To do something like this in mvc3, you would populate the tables using a foreach loop from your viewmodel items, ie
<table id="@Model.Table1.Name">
@{ foreach(var item in Model.Table1.Items){
<tr><td> @Model.Table1.RowText </tr></td>
}}
</table>
要支持这个例子中,你就会有一个视图模型定制MyTable的对象
To support this example you'd have a ViewModel with custom MyTable objects
public class MyTable{
public List<String> RowText {get;set;}
public string Name {get;set;}
}
和您的视图模型将看起来像
and your viewmodel would look something like
public class MyViewModel{
public MyTable Table1{get;set;}
public MyTable Table2{get;set;}
//and it would also include the properties for other elements on the page too
}
