Apache Tiles set html tag attribute using <put-attribute> value
I am using Apache Tiles 2.1 as my templating framework (along with Spring MVC).
I want to know how best to be able to set HTML attribute values from within my Tiles definitions file. For example I have a text box and want to be able to开发者_Python百科 set the maxlength attribute from within my definition. I expected the following to work -
<input id="nameField" type="text"
maxlength="<tiles:insertAttribute name='maxlength' />" />
using this definition -
<definition name="sprint-goal" >
<put-attribute name="maxlength" value="100" />
</definition>
But it seems that Tiles ignores the <insertAttribute/> tag if placed within a HTML tag. It works fine otherwise.
Note: I have tried using a ViewPreparer to set request-scoped values. This will work but is not exactly what I am looking for. I would like to easily set HTML attribute values from within a Tiles definition.
To set the value of html element attributes, your best bet is to use Expression Language. First, expose the tile attribute as a java variable using the tiles useAttribute tag. Then use '${}' to print the variable.
Example:
<tiles:useAttribute name="myMaxLength" id="maxLength" />
<input id="nameField" type="text" maxlength="${myMaxLength}" />

<put-attribute name="maxlength" value="100" type="string" />
I type isn't defined as "string" it would be taken as a URL to include...
