textinput

问题 Currently I have an input box which has the value "Current Website" When they click it I run this function: function clearMeHttp(formfield) { if (formfield.defaultValue == formfield.value) { formfield.value = "http://"; } }; It works fine if you click into the box, but if you tab into the box it just highlights the word "http://" which defeats the purpose of it unless they hit the right arrow key which I want to avoid. Thanks! Here's the other code: <input onblur="restoreMe(this)" onfocus=

问题 I need to put together an editable text area that has a custom caret (cursor) which is different from the default blinking vertical line. Is the caret a "skinnable" property of text input? Please note that I am not asking about the mouse pointer cursor which can be set using the CursorManager. Thanks. -Raj 回答1: No, the look and behaviour of the caret is controlled by the Flash player itself. There is no programmatic access to it. 来源： https://stackoverflow.com/questions/1785535/flex-how-to

问题 I'm designing a GUI for android with kivy. There are many TextInput-fields, most of them need some kind of validation. What I've found so far is, that on_text_validate would allow for plausibility checks, but only if the user leaves that field with ENTER, which is rarely the case in an android-environment. How can I achieve checks if the user sets the focus to another widget by tapping? Doing this (allways) with on_text seems a bit weird to me, but maybe it's possible. A simple example: how

问题 I have been seeing a weird lag in the text that is input into a textInput container in my flex mobile app. The issue occurs when I type in some text into a textInput then scroll in any direction. The entire screen and all objects seem to move, except for the text in the textInput. This becomes a really big issue when I select the textInput to begin typing and the softkeyboard appears and shifts the input which then places the cursor and the typed text somewhere else on the screen. It looks

问题 In my React/ Redux app, I have a text input with its default value retrieved via Ajax call. User can edit the default value in the input, and then submit the updated value by clicking on a 'submit' link. I'm struggling with using either uncontrolled or controlled inputs for this. Using uncontrolled input with defaultValue : the component doesn't get re-rendered when the data for default value comes back from initial Ajax call (detailed in official document here). So the input field is blank

问题 The below code does not work properly in iOS (iPhone 6). When I press ‘Push Me’, the word is not displayed completely and the cursor is also not shown. On further investigation, I found out that onChangeText and onContentSize change are not triggered. Pressing any key on the key board after pressing the ‘Push Me’ button displays the full word. I want the full word to be displayed when the button is clicked. It works, if I use value prop to update the TextInput. But I need to display formatted
