selectionchanged事件不工作 [英] selectionchanged event is not working
问题描述
我添加了listeners(selectedchanged)节点到下拉字段。 loadcontent事件正在触发,但是selectedchanged是不正常的。请在下面找到代码片段
choosechanged:
function字段,值){
var layoutoption =;
layoutoption = field.findParentByType('dialog')。form.findField('./ footerstyle')。getValue();
alert('layoutoption:'+ layoutoption);
if(layoutoption =='3'|| layoutoption =='4'){
field.findParentByType('dialog')。form.findField('./ leftPadding')。enable(this) ;
} else {
field.findParentByType('dialog')。form.findField('./ leftPadding')。disable(this);
}}
CQ.form.Selection API,您会发现当 selectionchanged 事件被触发时,以下参数将被传递给侦听器。
- :选择字段
- 值:所选字段的原始值
- isChecked :true / false,当选择类型为复选框时使用。
因此,您可以修改您的监听器,如下所示。
function(field,value){
var dlg = field .findParentByType( '对话');
//该值保存选择的值
if(value =='3'|| value =='4'){
//对话框类的getField()返回具有给定名称的字段
dlg.getField('./ leftPadding')。show();
} else {
dlg.getField('./ leftPadding')。hide();
}
}
CQ.Dialog 返回字段与给定的名称。如果存在多个具有相同名称的字段,则返回这些字段的数组。您可以根据需要显示()或隐藏()字段。
编辑:
CQ 5.4以某种方式t删除整个小部件,而不是仅删除输入字段,留下字段标签,说明等。
在这种情况下,可以使用以下功能。
function(field,value){
var dlg = field.findParentByType('dialog');
if(value =='3'|| value =='4'){
dlg.getField('./ leftPadding')。el.parent('。x-form-item') 。显示();
}
else {
dlg.getField('./ leftPadding')。el.parent('。x-form-item')hide();
}
}
I have two felds in my dialog, one is text field(leftpadding) and another is dropdown with four options(option 1, option 2, option 3, option 4).My requirement is to display/enable the textfiled when the user selects option 3 and option 4 only. I added listeners(selectionchanged) node to the dropdown field. loadcontent event is firing but selectionchanged is not working fine. Please find below for the code snippet
selectionchanged:
function(field,value){
var layoutoption = "";
layoutoption = field.findParentByType('dialog').form.findField('./footerstyle').getValue();
alert('layoutoption :'+layoutoption);
if(layoutoption =='3' || layoutoption =='4'){
field.findParentByType('dialog').form.findField('./leftPadding').enable(this);
}else {
field.findParentByType('dialog').form.findField('./leftPadding').disable(this);
}}
If you look at the CQ.form.Selection API, you would find that when the selectionchanged event is fired, the following arguments would be passed to the listener.
- this : The selection field
- value : The raw value of the selected field
- isChecked : true / false, used when the selection is of type checkbox.
Thus, you could modify your listener as shown below.
function(field, value) {
var dlg = field.findParentByType('dialog');
// the value holds the value of the selection
if(value =='3' || value =='4'){
// getField() of the dialog class returns the field with the given name
dlg.getField('./leftPadding').show();
}else {
dlg.getField('./leftPadding').hide();
}
}
The getField() method of the CQ.Dialog returns the field with the given name. In case more than one field with the same name exists, it returns an array of those fields. You can then show() or hide() the fields based on your requirements.
EDIT : CQ 5.4 somehow doesn't remove the entire widget, instead removes only the input field leaving behind the Field Label, Description etc.
In such cases the following function may be used.
function(field, value) {
var dlg = field.findParentByType('dialog');
if(value == '3' || value == '4') {
dlg.getField('./leftPadding').el.parent('.x-form-item').show();
}
else {
dlg.getField('./leftPadding').el.parent('.x-form-item').hide();
}
}
