Escape single/double quotes from Stripes action bean jquery

Question

I have a javascript function as below,

function check() {
    document.getElementById("customer.name").value = "${actionBean.customer.name}";

.....

}

The value ${actionBean.customer.name} might have ' or "" quotes. How can I escape this from the javascript method?

For eg, the actionBean.customer.name dynamically becomes "HI "I'M HOME""

Cheers!!

org.apache.commons.lang3.StringEscapeUtils can do that for you. It has a method escapeEcmaScript(String input).

Older versions in org.apache.commons.lang.StringEscapeUtils contain a similar method escapeJavaScript(String input).

I usually create a StringFunctions class, consisting of static functions, like wrapping the escapeEcmaScript function:

public static String escapeEcmaScript(String s) {
   return StringEscapeUtils.escapeEcmaScript(s);
}

Include the StringFunctions class in a tag library descriptor:

<taglib xmlns="http://java.sun.com/xml/ns/j2ee" version="2.0">  

    <tlib-version>1.0</tlib-version>  
    <short-name>tlb</short-name>  
    <uri>http://www.trilobiet.nl/taglib/trlbt</uri>  

    <function>    
        <name>escapeEcmaScript</name>    
        <function-class>
            com.trilobiet.apollo.stripes.viewhelpers.StringFunctions
        </function-class>    
        <function-signature>    
            String escapeEcmaScript(java.lang.String)    
        </function-signature>  
    </function> 

    <!-- more functions -->

</taglib>

Include the tag lib descriptor in jsp:

<%@ taglib prefix="tlb" uri="/WEB-INF/taglib/tlb.tld" %>

(Of course you are free to use any short-name and taglib prefix that sound logical to you.)

And use like so:

${tlb:escapeEcmaScript(actionBean.customer.name)}
