javascript - Sencha Touch 2: Change the text of an HTML button in itemTpl -


मेरे डेटाव्यू के लिए itemTpl में, मेरे पास निम्न पंक्ति है:

& lt; div Class = "btn" id = "colorbtn" uniqueId = "{id}" & gt; {[this.getcolorbutton (मान))}

मेरे श्रोता में मेरे पास है निम्नलिखित: 

  श्रोताओं: {element: 'element', प्रतिनिधि: '#colorbtn', tap: function (item, idx, el, evt) {// आप जिस आइटम को btnId = El.getAttribute ('अद्वितीयId'); //Ext.getCmp('colorbtn').setText( 'नया मान'); चेतावनी ("नमस्ते" + बीटीएनआईडी); }}

जैसा कि आप देख सकते हैं, मैं बटन को Ext.getcmp से प्राप्त करने का प्रयास कर रहा हूं और नए टेक्स्ट को सेट करता हूं, लेकिन यह त्रुटि फेंक रहा है अनक्यूट टाइप एरर: अपरिवर्तित की संपत्ति 'settext' पढ़ नहीं सकते क्या हासिल करने का एक तरीका क्या है जिसके बाद मैं हूं?

Ext.get () के साथ आपके ईवेंट में तत्व चर को लपेटें, यह Ext.dom को पुनः प्राप्त करेगा एलेमेंट ऑब्जेक्ट उसके बाद आप Ext.dom.Element के लिए उपलब्ध विधियों का उपयोग कर सकते हैं।

उदाहरण: 

  Ext.get (el) .setHtml ('नया मान');

नोट: अगर किसी ऑब्जेक्ट को AJAX या DOM के द्वारा उसी आईडी से बनाया गया है, तो स्वचालित रूप से ठीक करता है।

javascript - How to get MySQL query result returned using $.ajax -

I'm trying to update is a JavaScript, when you hover over an image, a devi Floats near your mouse, this information is stored in an .js file as an array, for example. text [0] = ["image 1", "data1"] text [1] = ["image2", "data2"] In the past, if the array change / add / delete the data it will need to upload a new copy .js file, if the data was attached / deleted, then the new image needs a change in .dwt file Which can update each file using the .dwt file as the main template, which can result in 20+ pages They are uploaded I thought that I can automate this record by using the database and using the database if they are active and use only mysql queries which are active, such a black app The database can be added and disabled, thus eliminating the need for every soft upload of the file. To do this, I had planned to store the information in the database and create the above array based on the results, by researching how to us...
