Question

我显示了一堆图像，我想编辑某个图像的细节。

我想通过突出显示来选择图像，然后单击edit按钮。

它已经在工作但我想知道，当我第一次点击图像时，它不会被突出显示但是第二次会突出显示。这是我的代码：

 mainApp.controller('employeeController', ['$scope', '$http', function($scope, $http) {
     $http.get(BASE_URL+'Employee/getAllEmployees').success( function(response) {
                       $scope.employees = response

     });
     $scope.setActive=function(empID){
         $('img').click(function(){
           $('.selected').removeClass('selected');
           $(this).toggleClass('selected');
           $('#edit_eq').prop('disabled',false)

         });

     }
}]);

这里是HTML部分：

 <button id="edit_eq" type="button" 
      class="btn btn-default" disabled><i class="fa fa-edit"></i> Edit Employee
    </button>
 <div ng-controller="EmployeeController" class="row placeholders">
   <div class="col-xs-6 col-sm-3 placeholder" ng-repeat="emp in employees | filter: name">
      <img src="<?php echo base_url();?>{{emp.image}}" style="height:150px;width:150px" ng-click="setActive(this)">
      <h4><a href="#viewEmp" data-toggle="modal">{{emp.lname}}, {{emp.fname}} {{emp.mname}}</a></h4>
      <span class="text-muted">{{emp.position}}</span>
    </div>

</div>

您的setActive功能click会在您event的每次点击时绑定新的<img /> <img />。这样它只会在第二次点击时起作用，因为它第一次再绑定ng-click="setActive(this)"。基本上这不是你想要完成的正确方法，因为你真正需要的唯一绑定是标记（ng-click）中的绑定。

事实上，<img />已经绑定了function，并且在它执行的$scope.setActive = function(empID) { //this get execute when <img /> gets clicked $('.selected').removeClass('selected'); $(this).toggleClass('selected'); $('#edit_eq').prop('disabled',false) };中，你必须只指定你想要它做什么，而不是一次又一次地绑定它

做这样的事情：

# functionfile
function Show-MsgBox {
  Write.Host "debugFUNC2"
  #usage:
  #Show-MsgBox -Prompt "This is the prompt" -Title "This Is The Title" -Icon Critical -BoxType YesNo -DefaultButton 1

  [CmdletBinding()]
  param(
    [Parameter(Position=0, Mandatory=$true)] [string]$Prompt,
    [Parameter(Position=1, Mandatory=$false)] [string]$Title ="",
    [Parameter(Position=2, Mandatory=$false)] [string]$Icon ="Information",
    [Parameter(Position=3, Mandatory=$false)] [string]$BoxType ="OkOnly",
    [Parameter(Position=4, Mandatory=$false)] [int]$DefaultButton = 1
  )
  [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.VisualBasic")
  switch ($Icon) {
    "Question" {$vb_icon = [microsoft.visualbasic.msgboxstyle]::Question }
    "Critical" {$vb_icon = [microsoft.visualbasic.msgboxstyle]::Critical}
    "Exclamation" {$vb_icon = [microsoft.visualbasic.msgboxstyle]::Exclamation}
    "Information" {$vb_icon = [microsoft.visualbasic.msgboxstyle]::Information}
  }
  switch ($BoxType) {
    "OKOnly" {$vb_box = [microsoft.visualbasic.msgboxstyle]::OKOnly}
    "OKCancel" {$vb_box = [microsoft.visualbasic.msgboxstyle]::OkCancel}
    "AbortRetryIgnore" {$vb_box = [microsoft.visualbasic.msgboxstyle]::AbortRetryIgnore}
    "YesNoCancel" {$vb_box = [microsoft.visualbasic.msgboxstyle]::YesNoCancel}
    "YesNo" {$vb_box = [microsoft.visualbasic.msgboxstyle]::YesNo}
    "RetryCancel" {$vb_box = [microsoft.visualbasic.msgboxstyle]::RetryCancel}
  }
  switch ($Defaultbutton) {
    1 {$vb_defaultbutton = [microsoft.visualbasic.msgboxstyle]::DefaultButton1}
    2 {$vb_defaultbutton = [microsoft.visualbasic.msgboxstyle]::DefaultButton2}
    3 {$vb_defaultbutton = [microsoft.visualbasic.msgboxstyle]::DefaultButton3}
  }
  $popuptype = $vb_icon -bor $vb_box -bor $vb_defaultbutton 
  $ans = [Microsoft.VisualBasic.Interaction]::MsgBox($prompt,$popuptype,$title)
  return $ans
} #end function

function mafunc {
  Write-Host "debugFUNC1"
  $timer.start()
  $timer
  return 0
}

# calling file

$timer = New-Object System.Timers.Timer
#$timer.interval = 1800000
$timer.interval = 30000
$timer.Enabled = $true
$timer.AutoReset = $False
$scriptsleep = 0
$timer.stop()

$ThirtyAction = {
  Write-Host "action"
  Write-Host "action2"
  if ((Show-MsgBox -Prompt "prompt" -Title "title" -Icon Critical -BoxType YesNo -DefaultButton 1) -eq "No") {
    Write-Host "debugNO"
  } else {
    Write-Host "debugYES"
    $timer
    $timer.stop()
    Show-MsgBox -Prompt "prompt" -Title "title" # standard promt = OKonly button
    $timer.interval=30000
    $timer.start()
    $timer
    Write-Host "timer start"
  }
}

Register-ObjectEvent -InputObject $timer -EventName Elapsed -SourceIdentifier ThirtySecTimer -Action $ThirtyAction

myfunc
