Question

我正在使用ng-init表达式将选定下拉列表中的值赋给viewModel。功能正常。但是它在浏览器控制台中显示了很多错误。任何人都可以帮我这个吗？

<div class="form-group">
                            <label class="control-label col-md-3">Approve Status:</label>
                            <div class="col-md-4">
                                <select ng-disabled="true" ng-init="{{obj.ApproveID=selectedApproveStatus.DropdownUtilityID}}" ng-model="selectedApproveStatus" data-ng-options="option.DropdownUtilityName for option in approveStatus track by option.DropdownUtilityID" class="form-control"></select>
                            </div>
                        </div>

Error: [$parse:syntax] Syntax Error: Token '{' invalid key at column 2 of the expression [{{obj.ApproveID=selectedApproveStatus.DropdownUtilityID}}] starting at [{obj.ApproveID=selectedApproveStatus.DropdownUtilityID}}].

ng-init的语法为ng-init="expression"，您不应将其包含在braces({{)
中

试试这个：

＆＃13;

<div class="form-group">
  <label class="control-label col-md-3">Approve Status:</label>
  <div class="col-md-4">
    <select ng-disabled="true" ng-init="obj.ApproveID=selectedApproveStatus.DropdownUtilityID" ng-model="selectedApproveStatus" data-ng-options="option.DropdownUtilityName for option in approveStatus track by option.DropdownUtilityID" class="form-control"></select>
  </div>
</div>

＆＃13;

ng-init总是在浏览器Consolde中给出错误
