How to Separate the Jquery response which contains STD_ERROR -

-

<पूर्व> $। Get ("/ student / studentnumber.php", $ ("myform")। Serialize () , फ़ंक्शन (डेटा) {चेतावनी (डेटा); यदि (डेटा.sबस्ट्रिंग (0,7) == 'STDERR') {//$ ("######################) {//$ ("#MYSPAN").text(data);}}};

उपरोक्त स्क्रिप्ट में मुझे "Studentnumber.php" से आने वाला PHP प्रतिसाद है। अगर "सही संख्या" दर्ज की जाती है तो "डेटा" फ़ील्ड में "छात्र नाम" शामिल होता है। एक गलत संख्या दर्ज की गई है, वह "एसटीडीईआरआर: एसएनओ नॉट वैलआईड" को प्रदर्शित करता है। अब यहाँ मैं एक गलत नंबर दर्ज होने पर केवल "एसएनओ वैलआईड" को नहीं भेजना चाहता। मैं "एसटीडीईआर:"

/ Div>

आप बंद हैं।

.substring () का सूचकांक कॉल 1 से बंद है।

इसे आज़माएं: 

  अगर (data.substring (0,6) == 'STDERR' ) {$ ("# MYSPAN")। पाठ (data.substring (7)); } और {$ ("# MYSPAN")। पाठ (डेटा); }

अपडेट: यदि आप $। Trim () का उपयोग करते हैं तो यह उत्तर अभी भी काम करेगा, अतिरिक्त सफेद से छुटकारा पाने के लिए अंतरिक्ष। 

  डेटा = $ .ट्रिम (डेटा);

अन्यथा, नीचे दिए गए उत्तर का उपयोग करें।

संपादित करें: आपकी टिप्पणी से, वहां की शुरुआत में एक स्थान है STDERR। उस स्थिति में, आपको अपने नंबरों पर वापस जाने की जरूरत है, और उस स्थान को तुलना के लिए STDERR स्ट्रिंग में जोड़ें।

इसे आज़माएं: 

  यदि (data.substring (0,7) == 'STDERR') {$ ("# MYSPAN")। पाठ (data.substring (8)); } और {$ ("# MYSPAN")। पाठ (डेटा); }

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...

Using Python + PyGTK Is there a signal / event way to change the window size? If so, then what is the easiest way to implement and use this signal. There is also one, so it answers the signal. Here's the minimum sample code: import gtk def (window): print 'I have resized'. W = gtk.Window () w.connect ('check-size', has been changed) w.show () gtk.main ()

c# - read full xml file data over tcp -

I'm developing an application that either the incoming data on the PC and then when I'm trying does it decodes the data to use the software with any sniffing have been stored in the dB and I can read it myself ... but my code .... this came in a format like 1651589240214931398151442251437622947132917620011138147205162160411201699123179148781675713921035101183865895219106213196222741589715384652061681391901278671232822552717812424975221242 11517622131122113236255230254211206911242051832545515823012124925217318223920523316923122925514321122343602492471242 ........ I have tried to use this System.Text.Encoding.ASCII.GetString (tcpHeader.Data) and it is working fine. But when I run it and wait for data (this is in XML format) I have found in many packages that it is difficult to read it again ... What should I do? Do I have to collect data from every packet, then add all to get the whole message? Or there is a library to do that in .net
