由 风格不统一 提交于 2019-11-29 15:16:42
问题 I have the following property file defined in one of my Spring (3.1) XMLs: <context:property-placeholder location="classpath:MyConfigFile.properties"/> I want to be able to define a second optional property file which will override the "MyConfigFile.properties" file and will get loaded instead of it.

Spring - Replacing the bean property values with new Property File values

由 ぃ、小莉子 提交于 2019-11-29 14:56:54
问题 I have a property file and using Spring property place holder, I set values to the Spring beans. Now, this property file may be modified during the run time. Is there a way to refresh the properties of the Spring beans with this newly modified property value? Especially, I have many singleton beans? How can I refresh them with the new values? Is there already a solution to this or should it be custom coded? If it doesn't already exist, can someone please give the best approach to achieve this

How to keep input placeholder visible when user is typing

由 烈酒焚心 提交于 2019-11-29 14:45:02
I have a new and intriguing requirement. Instead of the placeholder disappearing when the user starts typing, it should remain visible and shift over to the right hand side of the input box. Is this even possible with a standard HTML placeholder? How might I achieve this? Thanks I don't think that you can do it ONLY with standard placeholders, but you can use this example http://css-plus.com/2011/09/make-the-input-placeholder-user-friendly/ I am not sure if keeping placeholder visible on typing is possible or not but you can shift it to right by using this css: CSS .example:focus::-webkit

Text Field Tag Placeholder Returning As Value

由 依然范特西╮ 提交于 2019-11-29 11:19:53
问题 I have a form and inside the form there is a text_field_tag. It is written as this... <%= text_field_tag "search", :placeholder => 'Enter search term...' %> However, when the HTML is generated this returns in the page source... <input id="search" name="search" type="text" value="{:placeholder=>"Enter search term..."}" /> Why is it doing this and how do I fix it so that placeholder works? 回答1: The second parameter of the text_field_tag is the value. Give it nil to have it empty: <%= text_field

Html placeholder text in a textarea form

由 丶灬走出姿态 提交于 2019-11-29 11:11:37
On one of my websites I have created a form that collects the persons name, email and a description of their idea. I limited the characters of the description to 500 characters as I don't want to read a ton and I figured out how to have the text appear in the textarea before the user inputs what they want. Currently the user has to delete "Description of your idea" themselves but I want to add the placeholder class where it deletes what I have written in the textarea when they click the textarea I have looked on a few sites and couldn't figure out how to use it I placed it in my code, but

Swap placeholder text based on resolution (media query)

由 左心房为你撑大大i 提交于 2019-11-29 10:55:18
问题 I'm working on a responsive design. I've hit a bit of a wall with there not being enough space for an input box and it's label . So I have decided to hide the label on smaller screen sizes. At present it has the placeholder text your email inside it, but I want only on screens less than 400 (so up to 399px wide) a different place holder of Join our newsletter . I reckon there will need to be some JS to perform this, rather than anything with CSS. Essentially: if screen size less than 400:

HTML5 “placeholder” support

由 你离开我真会死。 提交于 2019-11-29 09:18:35
How can I find out if the browser supports the HTML5 placeholder tag, so I can decide whether to hook my jQuery placeholder plugin or not. var placeholderSupported = ( 'placeholder' in document.createElement('input') ); The variable placeholderSupported will be true if it is natively supported. Otherwise, it'll be set to false . thirtydot http://diveinto.html5doctor.com/everything.html#placeholder return 'placeholder' in document.createElement('input'); However, the jQuery plugin you're using might already be checking for native support - you might not need to do this yourself.
