在Adobe cq5对话框中的更改路径字段上填充选择框选项 [英] Populating select-box options on changing pathfield in dialog of Adobe cq5
问题描述
在我的一个对话框中,我有一个xtype为 pathfield的字段。根据此字段的值,我想更改选择框(xtype = selection,type = select)的选项。
In one of my dialogs, I have a field with an xtype of "pathfield". Depending on the value of this field, I want to change the options of the "select-box" (xtype="selection",type="select").
我使用了侦听器,并在 pathfield字段的事件 change和 dialogclose上添加了一个函数。
I have used listeners and added a function on events "change" and "dialogclose" for "pathfield" field.
我可以调用servlet,并且它正在发送带有选项的JSON响应,但是,我无法用这些选项填充选择框。
I can call the servlet and it is sending the JSON response with options, however, I am unable to populate the select-box with these options.
以下是dialog.xml
The following is code of the dialog.xml
<select-product jcr:primaryType="cq:Widget"
fieldDescription="Select Product (Product Details Page)"
fieldLabel="Select Product"
height="{Long}40" key="productPath"
name="./productPath"
style="height:21px"
width="{Long}350"
rootPath="/content/MY_MSM_PATH"
xtype="pathfield">
<listeners jcr:primaryType="nt:unstructured"
change="function(){ var selectBox=$('select[name=features]');
$.getJSON('/bin/featuresservlet?path=' + this.value,
function(jsonData){
$.each(jsonData, function(i,data){
$('<option>').val(data.value).text(data.name).appendTo('select[name=features]');
});
}); }"
dialogclose="function(){
var selectBox=$('select[name=features]');
$.getJSON('/bin/featuresservlet?path=' + this.value, function(jsonData){
$.each(jsonData, function(i,data){
$('<option>').val(data.value).text(data.name).appendTo('select[name=features]');
});
}); }" />
</select-product>
<features jcr:primaryType="cq:Widget"
fieldLabel="Select Features:"
key="features"
name="./features"
type="select"
xtype="selection" />
推荐答案
您可以使用选择xtype的set options方法。将您的侦听器修改为类似
you can use the set options method of the selection xtype. Modify your listener to something like this
dialogclose="function(pathfield){
var dialog = pathfield.findParentByType('dialog');
var selectBox = dialog.findByType('selection')[0]; //assuming this is the only selection you have
$.getJSON('/bin/featuresservlet?path=' + this.value, function(jsonData){
selectBox.setOptions(jsonData);
selectBox.doLayout(flase,false);
}); }"
您的servlet返回的数据必须采用以下格式:
The data returned by your servlet must be of the following format :
[
{
"value": "valueOfOption1",
"text": "textOfOption1"
},
{
"value": "valueOfOption2",
"text": "textOfOption2"
}
]
