提前选择好角度UI引导后专注于其他输入 [英] Focus on other input after typeahead-on-select angular-ui-bootstrap
问题描述
我对angular-ui引导程序有疑问:我有2个输入:
I have a problem with angular-ui bootstrap: I have 2 input:
<input type="text" ng-model="selected" uib-typeahead="state for state in states | filter:$viewValue | limitTo:8" typeahead-on-select="focusSuccessive($item, $model, $label, $event)" class="form-control">
<textarea class="form-control" id="message" rows="10" data-ng-model="caller.data.text" tabindex="25"></textarea>
在我的控制器中,我有一个函数 focusSuccessive($ item,$ model,$ label,$ event)",该函数应在选定后聚焦textArea.
And in my controller I have a function focusSuccessive($item, $model, $label, $event)" that should focus textArea after selected.
$scope.focusSuccessive = function($item, $model, $label, $event){
angular.element("#message").focus();
}
但是它不起作用,但是如果我按以下按钮:
But it doesn't work, But if I put a button like:
<button ng-click="focusSuccessive()">focus</button>
它可以正常工作,所以选择预输入后如何聚焦文本区域或输入?
It work, so How Can I focus a textarea or input after typeahead selected?
推荐答案
发生这种现象是由于typeahead-on-select中的回调引起的.它使您的元素集中,但由于此代码,输入再次集中了
This behaviour is happening because of callback in typeahead-on-select. It focuses your element but input gets focussed again due to this code
$timeout(function() {
element[0].focus();
}, 0, false);
您可以通过异步关注元素来解决此问题.
You can solve this by focusing your element asynchronously.
在您的focusSuccessive函数中,使用$ timeout并将文本区域集中在$ timeout内
In your focusSuccessive function use a $timeout and focus your textarea inside that $timeout
$scope.focusSuccessive = function($item, $model, $label, $event){
$timeout(function() {
document.getElementById('message').focus();
}, 100, false);
}
这将解决您的问题.
我不确定是否有其他方法可以解决此问题,而无需使用$ timeout
I am not sure that there is some other way to solve this issue which don't require using $timeout
编辑
我认为预先输入设置中有一个选项
I think there is a option in typeahead-settings
typeahead-focus-on-select
默认情况下将其设置为true,将其设置为false将禁用此行为,并且您不需要$ timeout.只需正常地关注您的元素
Which is set to true by default, setting it to false will disable this behaviour and you dont need $timeout. Just focus your element normally
<input type="text" ng-model="selected" uib-typeahead="state for state in states | filter:$viewValue | limitTo:8" typeahead-on-select="focusSuccessive($item, $model, $label, $event)" typeahead-focus-on-select=false class="form-control">
