javascript - unable to get parent reference in sencha touch when calling function is in html attribute -

-

I need to create a common method in the controller of the power touch so that other similar modules in the application can get those pieces . But now I'm stuck because I'm not seeing my solution (even after trying 100 times on Google) the thing is that the calling function is in the 'html' attribute, and now we have its original context In order to refer to all other siblings, take a look at the code below: 

  & lt; Ext.form.IFieldSet & gt; {// This only shows if the existing data is under "Other Income": 'Field', Title: 'Other Income', Item ID: 'Other IncomeFest', // Instruction: '& lt; HR class = "different" /> ', Items: [& lt; Ext.field.ISelect & gt; {Xtype: 'selectfield', name: 'BorrowerPositionFirstSet', label: 'Borrower Position', Store: 'BorrowerPositionSelectorStore', // UsePicker: incorrect, disabled: true,}, & lt; Ext.field.ISelect & gt; {Xtype: 'selectfield', name: 'I type typeist', label: 'type of income', store: 'iTiveActiveStoreStore', // usagePicker: wrong, disabled: true,}, {xtype: 'textfield', name: 'DescriptionFirstset' label: 'monthly amount', disabled: true,}, & lt; Ext.form.ifild & gt; {Xtype: 'description', disabled: true,}, {xtype: 'numberfield', name: 'monthly statement floorSat', label: 'field', label: '', // This is the HTML feature of which I talk about I am ... html: '& lt; A href = "#" onclick = "event.preventDefault (); App.app.getController (\ 'Lead.leadsListController'). OnClickDelete (this)" class = "ta-textlink deleteLink" & gt; Remove & lt; / A & gt; & Lt; A href = "#" onclick = "event.prevent default (); App.app.getController (\ 'Lead.leadsListController \') onClickEdit (this)" class = "ta-textlink editLink" & gt; Edit & lt; / A & gt; '}]   
 As you can see that the calling functions are inside HTML and I do not want to use' Parent node '(which is pure JavaScript) because I had to do something This:  
  var parentRef = (ref.parentNode.parentNode.parentNode .....);   
 And you can see that this is just nonsense! Please help Sencha developers to get the solution for this. How can I get reference  Item ID: 'Other InInfoFirstSet'  through my children?   
 
 
 Why do not you use a button (or two) for it? Sounds like a little CSS and the button will be trick. Apart from this you can actually use it inside your controller. Fieldsets do not mean that you can not use buttons.  
 Hint: Never try to call an administrator out from the outside.  
 If you actually use field and one click event, use the following code (Do not forget, this is not my priority, because it can be well written in ST with two buttons!) :  
  & lt; Ext.form IField & gt; {Xtype: 'field', label: '', // This is the html attribute I'm talking about ... html: '& lt; A href = "#" onclick = "event.preventDefault (); ' + 'Extension' ('form') fireEvent ('Delete') '+ //   
 and inside the controller  
  config: {refs: {myView: '.myView', // the original view that you have created: ' .myview .form '}, Control: {form: {delete:' onDelete ', // & lt; & Lt; & Lt; & Lt; Here you edit the event: 'onEdit'}}}, onDelete: function () {}, onEdit: function () {}

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
