realtime update text in javascript by same id -


मैं आईडी = "b" में टेक्स्ट कैसे अपडेट करूं? 

  & lt; स्क्रिप्ट टाइप = "टेक्स्ट / जावास्क्रिप्ट" & gt; फ़ंक्शन updateb () {var a = document.getElementById ("a")। मान; Var b = document.getElementById ("b")। InnerHTML = एक * 10; } & Lt; / script & gt; & Lt; इनपुट प्रकार = "टेक्स्ट" id = "a" name = "a" मान = "10" onKeyUp = "updateb ();" / & Gt; & lt; p id = "b" नाम = "b" & gt; & lt; / p & gt; & Lt; इनपुट प्रकार = "टेक्स्ट" id = "a" name = "a" मान = "20" onKeyUp = "updateb ();" / & Gt; & lt; p id = "b" नाम = "b" & gt; & lt; / p & gt; & Lt; इनपुट प्रकार = "टेक्स्ट" id = "a" name = "a" value = "30" onKeyUp = "updateb ();" / & Gt; & lt; p id = "b" नाम = "b" & gt; & lt; / p & gt;

1) आईडी हमेशा किसी पृष्ठ में अनूठी होंगी।

< P> 2।) GetElementById हमेशा एक ही आईडी के साथ एक ही तत्व देता है यदि समान मूल्य के साथ कई आईडी हैं

3)। ऊपर प्रश्न के लिए आप getElementsByName प्राप्त कर सकते हैं। यह एलेमेंटबीआईडी ​​को एक अंतर के साथ मिलना बहुत समान है, यह आपको समान नाम वाले सभी तत्वों को देगा। यदि आप

x = document.getElementsByName ("b");

x [0] में पहले एक होगा

x [1] में 2 एक

x [2] में तीसरा होगा

यदि आप चाहते हैं कि यह getElementById द्वारा किया जाए तो उर तत्व आईडी को किसी भी अन्य अद्वितीय नाम की तरह बदलें: 

  & lt; script type = "text / javascript" & gt; फ़ंक्शन अपडेटब (एसआरसी) {var a = Src.value; Document.getElementById ("b" + Src.id.substr (1))। InnerHTML = एक * 10; } & Lt; / script & gt; & Lt; इनपुट प्रकार = "टेक्स्ट" id = "a1" नाम = "a" मान = "10" onKeyUp = "updateb (यह);" / & Gt; & lt; p id = "b1" नाम = "b" & gt; & lt; / p & gt; & Lt; इनपुट प्रकार = "टेक्स्ट" id = "a2" नाम = "a" मान = "20" onKeyUp = "updateb (यह);" / & Gt; & lt; p id = "b2" नाम = "b" & gt; & lt; / p & gt; & Lt; इनपुट प्रकार = "टेक्स्ट" id = "a3" नाम = "a" मान = "30" onKeyUp = "updateb (यह);" / & Gt; & lt; p id = "b3" नाम = "b" & gt; & lt; / p & gt;

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
