标签: selected

我想做这样的事情来勾选checkbox使用jQuery:

$(".myCheckBox").checked(true);

要么

$(".myCheckBox").selected(true);

这样的事情存在吗？

我为按钮的状态Normal,Highlighted和Selected设置了一个图像,但是当按钮处于选中状态时我按下/突出显示它我没有看到我突出显示的图像而只是灰色的图像.选择按钮时,是否可以将图像设置为高亮显示状态？

我的代码:

[button setImage:[UIImage imageNamed:@"normal.png"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"pressed.png"] forState:UIControlStateHighlighted];
[button setImage:[UIImage imageNamed:@"checked.png"] forState:UIControlStateSelected];

当我做:

[button setSelected:YES];

并按下按钮,"pressed.png"图像不会选择.

我正在使用Angular JS,我需要使用angular JS设置下拉列表控件的选定选项.请原谅我,如果这很荒谬,但我是Angular JS的新手

这是我的html的下拉列表控件

 <select ng-required="item.id==8 && item.quantity > 0" name="posterVariants"
   ng-show="item.id==8" ng-model="item.selectedVariant" 
   ng-change="calculateServicesSubTotal(item)"
   ng-options="v.name for v in variants | filter:{type:2}">
  </select>

填充后,我得到了

 <select ng-options="v.name for v in variants | filter:{type:2}" ng-change="calculateServicesSubTotal(item)"
ng-model="item.selectedVariant" ng-show="item.id==8" name="posterVariants"
ng-required="item.id==8 &amp;&amp; item.quantity &gt; 0" class="ng-pristine ng-valid ng-valid-required">
    <option value="?" selected="selected"></option>
    <option value="0">set of 6 traits</option>
    <option value="1">5 complete sets</option>
</select>

如何设置value="0"要选择的控件？

我想知道这些州有什么不同.我没有找到任何网页澄清这一点.

在我的用户单击按钮后,我希望该按钮在执行网络操作期间保持推送状态.网络操作完成后,我希望按钮返回其默认状态.

我试过调用 - [UIButton setSelected:YES]在按钮按下之后(通过相应的调用 - [UIButton setSelected:NO]在我的网络操作完成后),但似乎没有做任何事情.如果我打电话也一样setHighlighted:.

我想我可以尝试交换背景图像,以表示网络操作期间的选定状态,但这似乎是一个黑客.有更好的建议吗？

这是我的代码的样子:

- (IBAction)checkInButtonPushed
{
    self.checkInButton.enabled = NO;
    self.checkInButton.selected = YES;
    self.checkInButton.highlighted = YES;
    [self.checkInActivityIndicatorView startAnimating];
    [CheckInOperation startWithPlace:self.place delegate:self];
}

- (void)checkInCompletedWithNewFeedItem:(FeedItem*)newFeedItem wasNewPlace:(BOOL)newPlace possibleError:(NSError*)error;
{
    [self.checkInActivityIndicatorView stopAnimating];
    self.checkInButton.enabled = YES;
    self.checkInButton.selected = NO;
    self.checkInButton.highlighted = NO;
}

我需要强制DataGridView显示所选row.

简而言之,我有一个根据键入的内容textbox更改DGV选择textbox.发生这种情况时,选择会更改为匹配row.

不幸的是,如果所选row内容不在视图中,我必须手动向下滚动才能找到所选内容.有谁知道如何强制DGV显示所选row？

谢谢!

这是我的模型:

public class NewsCategoriesModel {
    public int NewsCategoriesID { get; set; }        
    public string NewsCategoriesName { get; set; }
}

我的控制器:

public ActionResult NewsEdit(int ID, dms_New dsn) {
    dsn = (from a in dc.dms_News where a.NewsID == ID select a).FirstOrDefault();
    var categories = (from b in dc.dms_NewsCategories select b).ToList();
    var selectedValue = dsn.NewsCategoriesID;
    SelectList ListCategories = new SelectList(categories, "NewsCategoriesID", "NewsCategoriesName",selectedValue);

    // ViewBag.NewsCategoriesID = new SelectList(categories as IEnumerable<dms_NewsCategory>, "NewsCategoriesID", "NewsCategoriesName", dsn.NewsCategoriesID);
    ViewBag.NewsCategoriesID = ListCategories;
    return View(dsn);
}

然后我的看法:

@Html.DropDownList("NewsCategoriesID", (SelectList)ViewBag.NewsCategoriesID)

当我运行时, …

启动应用程序时,不会选择任何行.但我想表明第一行已被选中.

这该怎么做？我需要设置一行的颜色JTable吗？

更新:我尝试了table.setRowSelectionInterval(0,0).我知道它应该工作,但有一条错误消息:

// Doesn't work
cell.selectionStyle = .Blue

let cellBGView = UIView()
cellBGView.backgroundColor = UIColor(red: 0, green: 0, blue: 200, alpha: 0.4)
cell.selectedBackgroundView = cellBGView

任何答案如何设置所选单元格的背景颜色？

如何在不裁剪的情况下看到矩形选框的选区大小？在paint.net中非常容易,但我必须在photoshop cs 5.在选择区域时,我应该能够看到所选区域的尺寸.我怎样才能做到这一点 ？

此外,当我选择具有矩形选框的区域时,我想要看到该区域的位置或者至少我需要能够看到像素位置.位置意味着它在图像中的位置像顶部55px左45px谢谢.
