How to get length in Javascript of an array of Form text fields -


मेरे पास यह HTML कोड है: 

  & lt; form id = "form1" name = "फॉर्म 1" विधि = "पोस्ट" एक्शन = "" & gt; एक & lt; इनपुट प्रकार = "पाठ" नाम = "आइटम []" मान = "1" / & gt; & Lt; br / & gt; बी एंड एलटी; इनपुट टाइप = "टेक्स्ट" नाम = "आइटम []" मान = "1" / & gt; & Lt; br / & gt; सी & lt; इनपुट प्रकार = "टेक्स्ट" नाम = "आइटम []" मान = "1" / & gt; & Lt; / प्रपत्र & gt;

मुझे पाठ फ़ील्ड सरणी के बाहर की लंबाई को व्याकरण के रूप में खींचने के लिए प्रतीत नहीं हो रहा है, क्या ऐसा करने के लिए कुछ स्पष्ट सादा जावास्क्रिप्ट रास्ता है (कोई जेक्जरी नहीं है)? मैंने कोशिश की 

  & lt; script language = "javascript" & gt; // इन संयोजन सतर्क (document.form1.item.length) की कोशिश की; चेतावनी (document.form1.item [] लंबाई।); चेतावनी (document.form1.elements [ 'आइटम'] लंबाई।); चेतावनी (document.form1.elements [ 'आइटम []'] लंबाई।); & Lt; / स्क्रिप्ट & gt;  

  var inputCount = document.getElementById ('फॉर्म 1')। GetElementsByTagName ( 'इनपुट') लंबाई।

ध्यान दें, कड़ाई से बोलते हुए, आपके इनपुट तत्व एक सरणी का गठन नहीं करते हैं। वे डोम में नोड हैं, इसलिए उन्हें उन्हें एक सरणी के रूप में खोजना होगा।

मुझे पता है कि आपने "कोई jQuery नहीं" कहा है, लेकिन इस दिन और उम्र में यह वास्तव में मुझे परेशान करता है जब लोग प्रयोग करने में प्रतिरोधी होते हैं ऐसा उपकरण वे समस्याओं के बहुत सारे को हल करते हैं जिन्हें आप अन्यथा समाप्त कर देंगे।

c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -

Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title? I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on. The first thing to look at after the code is that I stand by: The sample uses the main.cpp: qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show (); Some name changes in my name. CPP qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml"))); I'm not sure that the difference in using QQmlApplicationEngine...

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net - getting a value of selected radiobutton in LoadViewState -

Can I get the value of a selected radio button in the LoadViewState event of WebControl and how? All components are generated in codebehind, so I have those controls: Radiobutton list RLL; LISTIME leon; List liTwo; At this time I was stuck on that the overloaded loadviolet is not being implemented protected override zero load vivestat (object o) {action = Rbl.SelectedValue; Verb 2 = rll Selected item. value; Base.LoadViewState (O); } You also need to override the SaveViewState method. Radio button AFAIK has problems in saving their selected state.
