javascript - How can I clear this text box? -

-

निम्न मिथ्रिल कोड इसका एक मूल्य खींचकर एक टेक्स्ट बॉक्स को रिक्त करने के लिए है यह पाठ बॉक्स को साफ़ नहीं करता है (या कुछ भी करता है) मैं इसे कैसे काम कर सकता हूं?

ध्यान दें कि यदि मैं इस रेखा को बदलता हूं: 

  this.newItemName ("");

से: 

  this.newItemName ("abc");

फिर पाठ बॉक्स एक नए मान के साथ अद्यतन किया गया है। लेकिन मैं इसे स्पष्ट करना चाहता हूं। 

  var ऐप = {नियंत्रक: फ़ंक्शन () {this.newItemName = m.prop (""); This.makeNewItem = फ़ंक्शन (नाम) {यदि (नाम) {this.newItemName (""); }}}, देखें: फ़ंक्शन (ctrl) {वापसी मी ("div", [m ("span", "new item"), मी ("इनपुट", {type: "text", onchange: m.withAttr ( "मान", ctrl.makeNewItem.bind (ctrl)), मान: ctrl.newItemName ()})]); }}; एम। मॉड्यूल (document.body, एप);

आपका कोड काम करने के लिए प्रतीत होता है:

यह संभव है कि आप मिथ्रिल के एक पुराने संस्करण का उपयोग कर रहे हैं।

ऐसे प्रमाण को संतुष्ट करने के लिए नीचे दिए गए कोड: 

  var ऐप = {नियंत्रक: फ़ंक्शन () {this.newItemName = m.prop ( ""); This.makeNewItem = फ़ंक्शन (नाम) {यदि (नाम) {this.newItemName (""); }}; }, देखें: फ़ंक्शन (ctrl) {वापसी मी ("div", [m ("span", "new item"), मी ("इनपुट", {type: "text", onchange: m.withAttr ("value ", Ctrl.makeNewItem.bind (ctrl)), मान: ctrl.newItemName ()}))); }}; एम। मॉड्यूल (document.body, एप);

How to access user directory in lazarus? -

After I am trying to open file changelog.txt and it does not matter if I open it Need to have the user open it though it is always located in the ~ / directory. Enter the file here. Here is my code: Process TForm1.FormCreate (From: TObject); Var myFile: textfile; Line: String; Start AssignFile (myFile, '~ / changelog.txt'); Reset (myFile); While EOF (MyFile) does not readLn (myFile, Line); Label3.Caption: = (Label3.Capttion + Line + # 13 # 10); End; CloseFile (myFile); End; This does not work, however, if I replace ~ with the actual user name, then it works, however, I use the username of each user Can not know which will run my program. Any idea how can I get the username that started the program? ! Thanks Edit1: I have tried this, but this also includes a new line: RunCommand ('/ bin / bash', ['- - C ',' Whoami '], users); This is normal. The concept of "~" is an shell level and thus requires a separate shell elev...

I am practicing using Codepean and my gallery was running well but I am trying to add the last line of images and it is all messing up and I do not know why For some reason, when I try to add that chess board it all gets worse. I am still very new so I hope to learn a lot. Thank you. [1]: http://codepen.io/zenturtle/pen/ezDGC Margins are causing issues when you use margins in the position of an element, then you push the elements around it too. Use a solution: Status: Relative and then use Positioning Properties: Above , Below , left , right example: #chess {status: relative; Left: 555px; } Another solution is to use status: absolute . Location Location: Relative on & lt; Div id = "perimeter" & gt; Status: Full on every Example: #chess {status: full; Bottom: 122px; Correct: 230px; } Similarly you are in the position of chess image...
