jquery - javascript scope issue -

-

कोड स्निपेट निम्नानुसार है: 

  $ (this) .parents ('td: first '।) .next () लगता है (' विकल्प ') customizeMenu (।' myMenu2 ');

यह काम करता है, लेकिन: 

  var श्रोता = समारोह () {$ (this) .parents ('td: first')। Next () .find ( 'विकल्प') customizeMenu ( 'myMenu2')। }; श्रोता ();

काम नहीं कर रहा है, क्यों और कैसे इसे ठीक करें?

'यह' एक समारोह में डालते समय एक ही ऑब्जेक्ट को इंगित नहीं करता है, यह वर्तमान फ़ंक्शन को इंगित करता है (आपके मामले में 'श्रोता')। इसके बजाय एक पैरामीटर के रूप में इसे ले लें, यदि वह एक विकल्प है (यह आप पर निर्भर करता है कि आप अपने फ़ंक्शन को कैसे कहते हैं)। 

  var listener = function (obj) {$ (obj) .parents ('td : पहले '।।) अगले () लगता है (' विकल्प myMenu2 ');') customizeMenu (। ' }; श्रोता (this);

Instead you want to do this, create your UIPickerView interface builder and have it in your view controller Connect to the outlet. Add it as a subview of your main view and set its frame coordinates so that it is offset right below the edge, x = 0, y = 480 Then, when you want to display a picker, animate it like something with the screen: [UIView startup permissions: zero reference: zero]; [Color picture setfr...

java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -

There is an object like "set" in Java that can contain only unique string values, but it also includes a count Is the number of string value in number? This idea is simple. A data set, ALA ... ABBCCC I will set the text of each line set- I want to add to the object every time a non-unique text is added to the set, I also want to show a numeric value associated with the set to show how often it was added. So if I run it on the above data then set output will be something like this: A: 1B: 2C: 3 Any ideas? Maps & lt; String, integer & gt; add public null (strings) {if (map.containsKey (s)) {map.put (s, map.get (s) + 1); } And {map.put (S, 1); }}
