Question

I noticed something when I was attempting to use remoteField ajax tag in grails. When I enter an ampersand (&), that value is not recognized in my controller when obtaining the parameter value.

Example: I will type Cat & Dog
What I see: Cat

How can I avoid this? Is this a known bug? I couldn’t find anything online about this.

Edit

I’m pretty sure this is due to url encoding and parameters, since an ampersand is usually a parameter delimiter. Just not sure how to get around this.

<g:remoteField action="getName" update="testDiv" paramName="search" name="nameSearchResults" value="" />

Controller:

def getName() {
    println "Search result = " + params.search
    //When typing "Cat & Dog" I get:
    //Search result = C
    //Search result = Ca
    //Search result = Cat
    //Search result = Cat 
    //Search result = Cat
}

Have you tried URL encoding the text in your remoteField?

I would recommend adding a before property with JavaScript to URL encode the input:

<g:remoteField action="getName" update="testDiv" paramName="search" name="nameSearchResults" value="" before="encodeURIComponent(this.value); return true;" />

You will then have to decode it in the controller.
