javascript - removing and appending a node -

-

मैं नीचे span तत्वों से div (< कोड> & lt; div id = 'foo' & gt; ) और उनमें से प्रत्येक के बजाय नए बनाए गए नोड्स को जोड़ें।

मैं div के सभी बच्चों को पार करने के लिए एक पाश का उपयोग कर रहा हूं , और प्रत्येक नोड के लिए मैं इसे removeChild से हटा रहा हूं और एक नव निर्मित नोड को जोड़ रहा हूं।

मुझे ओ / पी के रूप में 

  & lt; div id = 'foo' & gt; & Lt; स्पैन & gt; नया पाठ & lt; / SPAN & gt; & Lt; / div & gt;

मुझे ओ / पी जैसा निम्न प्रकार है 

  & lt; div id = 'foo' & gt; & Lt; स्पैन & gt; नया पाठ & lt; / SPAN & gt; & Lt; स्पैन & gt; नया पाठ & lt; / SPAN & gt; & Lt; स्पैन & gt; नया पाठ & lt; / SPAN & gt; & Lt; / div & gt;

समस्या का कोड निम्नानुसार है 

  & lt;! DOCTYPE HTML PUBLIC "- // W3C // DTD एचटीएमएल 4.0 ट्रांसक्रिप्शन // एन" & gt ; & LT; एचटीएमएल & gt; & Lt; HEAD & gt; & Lt; title & gt; नया दस्तावेज़ & lt; / TITLE & gt; & Lt; मेटा नाम = "जेनरेटर" CONTENT = "EditPlus" & gt; & Lt; मेटा नाम = "लेखक" सामग्री = "" & gt; & Lt; मेटा नाम = "कीवर्ड" CONTENT = "" & gt; & Lt; मेटा नाम = "विवरण" सामग्री = "" & gt; & Lt; / HEAD & gt; & LT; body & gt; & Lt; div id = 'foo' & gt; अनुवाद की दुनिया में & lt; SPAN & gt; आपका स्वागत है। & Lt; / SPAN & gt; & Lt; SPAN & gt; इसे प्रयोग करने के लिए धन्यवाद & lt; / SPAN & gt; & Lt; SPAN & gt; फिर से जाएं & lt; / SPAN & gt; & Lt; / div & gt; & Lt; तालिका सीमा = "0" कोशिकाक्षेत्र = "5" सेलपैडिंग = "0" वर्ग = "लिपी-हैदर-लोगो-मेन्यू" & gt; & LT; टीआर & gt; & Lt; td align = "left" & gt; & LT; स्पैन & gt; हैलो & lt; / स्पैन & gt; & Lt; / टीडी & gt; & Lt; td align = "left" & gt; विश्व पर्याप्त नहीं है & lt; / td & gt; & Lt; / टीआर & gt; & Lt; / तालिका & gt; & Lt; div & gt; & lt; a href = "एए" id = "id" & gt; यह एक परीक्षण है & lt; / a & gt; & lt; / div & gt; & LT; स्क्रिप्ट & gt; Var तत्व = document.getElementById ('foo'); Seg = document.createElement ('SPAN'); Root_1_SPAN_1_text = document.createTextNode ('नया टेक्स्ट'); seg.appendChild (root_1_SPAN_1_text); यदि (element.hasChildNodes ()) {var children = element.childNodes; के लिए (var i = 0; i & lt; children.length; i ++) {यदि (बच्चों [i] .nodeName == "# text") {continue; } Element.removeChild (बच्चों [i]); element.appendChild (SEG); }; }; & Lt; / स्क्रिप्ट & gt; & Lt; / body & gt; & Lt; / एचटीएमएल & gt;

अग्रिम धन्यवाद

आप फिर से जोड़ रहे हैं हर बार एक ही नोड, जो इसे स्थानांतरित करता है (यह इसे कॉपी नहीं करता है)

इसे बदलें: 

  element.appendChild (seg);

इस 

  element.appendChild (seg.cloneNode (सच));

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
