jQuery - Determine user vs programmatic event -

-

मेरे पास & lt; select & gt; है और मैं change () घटना जब उपयोगकर्ता चुनिंदा विकल्प को बदलता है तो मैं कई कार्यों की एक श्रृंखला करना चाहता हूं। लेकिन, अगर मैं $ (item) .trigger ('change') के माध्यम से बदलाव को ट्रिगर करता हूं तो मैं कार्यवाही की शृंखला को निष्पादित नहीं करना चाहता।

मैं एक अधिभार देखता हूं मापदंडों। मुझे यकीन नहीं है कि यह काम करेगा क्योंकि मैंने एक कस्टम इवेंट नहीं लिखा है। तो, उपयोगकर्ता द्वारा निकाल दिया गया घटना और मेरा प्रोग्राममैटिक निकाल दिया गया ईवेंट के बीच अंतर को निर्धारित करने के लिए मुझे क्या करना चाहिए?

ऐसा करने का एक त्वरित और गंदे तरीका है: 

  var progChange = false; $ ('चुनें')। परिवर्तन (फ़ंक्शन () {if (! ProgChange) {// उपयोगकर्ता कार्रवाई ...} progChange = false;}); फ़ंक्शन कॉल सेलेक्ट चेंज () {progChange = true; $ ( 'चुनें') को बदलने ()।; }   
 आप इसे अनिवार्यतः उसी तरह से  ट्रिगर  विधि से कर सकते हैं, और यह वैश्विक को खत्म कर देगा, जो एक अच्छी बात है:  
  $ ('select')। परिवर्तन (फ़ंक्शन (इवेंट, प्रॉजेक्ट) {if (! ProgChange) {// उपयोगकर्ता क्रियाएं}}}); $ ('चयन करें')। ट्रिगर ('परिवर्तन', [सच]);

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

javascript - What is an alternative to using getElementByClass for hiding multiple elements? -

-
I have a page with some links that I would like to be able to toggle with two buttons. It works with a link using getElementById, but I need to toggle some of those groups. I started with it, but it failed to work. I've heard that GetElementByClass has worked with everything but IE, but I'm using Opera 11.5 and it still does not work. I've searched a bit, but I'm new to some JavaScript and most of the explanation is not understood. Does anyone help me with a simple option, or can I help me fix the problem I've made? This is a test page I was using. & lt; Head & gt; & Lt; Script type = "text / javascript" & gt; Function hideNames () {document.getElementByClass ("WebName"). Style.display = "none"; } Function ShowName () {document.getElementByClass ("WebName"). Style.display = "inline"; } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; P class = "web...

c - Selecting a file randomly from a file system -

-
This question is related. I need to work on files and directories randomly as a file logic, such as rename, write, read etc. What I was planning to do, was to list all the files and directories along with their paths randomly to choose from this list. But, as the files and directories are created and destroyed in the actual file system, the list should also be updated. I am able to update the list and keep it inadequate in this way and it should also be atom so that the operation can not access any file later that was removed from the previous operation. Can you suggest that there is a different way of choosing files..to somehow integrate it with the file system ... but how do we know about the files? Thanks I'm Michael J. Barber's answer has found something particularly interesting, but due to my dragon ignorance I can not follow it completely You do not want to try to keep a list of files, when the file system is ok you should be able to correct it from C.
