When I display a WebView , I don't see the soft keyboard popping up. The hard keyboard also doesn't work! What are the usual shortcomings.

由 喜夏-厌秋 提交于 2019-11-26 21:29:29
问题 I am calling a function whenever someone press enter in the textarea . Now I want to disable new line or break when enter is pressed. So new line should work when shift + enter is pressed.

How to append text to '<textarea>'?

由 旧街凉风 提交于 2019-11-26 21:14:57
问题 I have <textarea> where user can type in his message to the world! Below, there are upload buttons... I would love to add link to uploaded file (don't worry, I have it); right next to the text that he was typing in. Like, he types in 'Hello, world!', then uploads the file (its done via AJAX), and the link to that file is added in next line to the content of <textarea> . Attention! Is it possible to keep cursor (place where he left to type) in the same place? All that may be done with jQuery..

Force spell check on a textarea in WebKit

由 好久不见. 提交于 2019-11-26 20:59:02
问题 I'm creating a browser based QC/data entry app that will let people edit OCRed files, which naturally have tons of errors. Chunks of data are put in textareas so they can be checked, but the red underlines only appear when the user manually puts the cursor in a misspelled word. Is there a way to force WebKit to add the little red spell check underlines to textareas? 回答1: Essentially you need to use the selection api to move the insertion point over each word to get Safari to highlight it.

Max characters in textarea with jquery

由 百般思念 提交于 2019-11-26 20:23:07
问题 I have the following code, and I'm kind of stuck on what to do next. The idea is when you enter text into a text area a counter tells you how many characters you have left. Once you get to the max characters I want to stop allowing characters to be entered, or delete all the characters that were entered so there are only 10 characters in the text area. I know I have to put the code where it says alert("LONG"); but I'm not quite sure what. var maxLen = 10; console.log("Start"); $('#send-txt')
