[Mohammad Haji Rajab Ali，修改在11 年前。]

Hi,
I have wrote a portlet and use serveResource() for convert text to speech,
but i can not send text by document.getElementById().value in value at tag
onClick="location.href = '<portlet:resourceURL><portlet:param name="msg" value="<script languege=javascript>document.getElementById("msg").value;<script/>" /></portlet:resourceURL>'"
please help how can i send textbox.text to value of tag serveResource.

Hi Mohammad,

Try putting the required text box in form, and submit the form onClick with resourceURL, this will pass the msg as request param.

Thanks and Regards,

Mohammad, What you are trying is incorrect. You are trying to pass a javascript value to java before it is generated. Instead, call a javascript function on click. Construct the url(without the msg param). You should be using ajax for calling serveresource() method. So, send that msg param with Ajax parameters. like this..
$.post(url,{msg:"my masage"},function(data){

});

Hi sheela,

resourceResponse.setContentType("application/json");
		resourceResponse.setCharacterEncoding("UTF-8");
		resourceResponse.getWriter().write(jsonFeed.toString());

you can use this.
and you can put your data like

JSONObject jsonFeed = JSONFactoryUtil.createJSONObject();
jsonFeed.put("data", keyValues);

Then how to go next .jsp page..from serveResource()

Like in processAction()..we use actionResponse.setRenderParameter("jspPage","/result.jsp");

Hi,
You don't go to a different page using serverResource(). It is basically ajax call to refresh a portion of your jsp page.
you create a resource url first, in your jsp page like this
<portlet:resourceURL var="variable1" id="identification1" escapeXml="false" />

write ajax function,
ajax.request({
url:"${variable1}",
param:{
param1:"hi"
},
success:function(response){
alert("hi");
}

in your controller if your portlet is spring mvc
@ResourceMapping(value="identification1")
// your method here

you can open your response in a new window using anchor tag,
<a target="_blank" href="${variable1}"
you don't need to write ajax function in this case.

hope it helps
Thanks

$.post(url,{msg:"my masage"},function(data){

});

Question to Mr Ravi Kumar Gupta - DOES LIFERAY SUPPORT '$', what I know it does not - one has to use like this 'jQuery.post(url,,)' - can you explain '$' ??

[David H Nebinger，修改在11 年前。]

$ was (is) a shortcut for jQuery, but you should not use the $ as I believe 6.x has it as a shortcut for AUI...

Stay away from the $ as it will just make your life difficult.

Hi David,

you are right , some days ago I had a same problem with "$" but after that instead of using "$" I put "jQuery" and it works.!

HI team,

I am facing issue including jsp page using serveResource(),

my scenario I have 3 tabs with images onclick of each tab i am including jsp page..

I am not using liferay tabs....using jquery tabs:

so

<portlet:resourceurl var="fetchJsp">

    <portlet:param name="fetchJsp" value="/html/vital/single.jsp" />

</portlet:resourceurl>

[b]IN action file:[/b]

	public void serveResource(ResourceRequest resourceRequest,
			ResourceResponse resourceResponse) throws IOException,
			PortletException {
		 String jspPage = resourceRequest.getParameter("fetchJsp");
		    System.out.println("jspPage==&gt;"+jspPage);
		    if (jspPage != null) {

		    	include(jspPage, resourceRequest, resourceResponse, PortletRequest.RESOURCE_PHASE);
		    	
		       
		    }
		    else {
		        super.serveResource(resourceRequest, resourceResponse);

	}
In jsp page:


<div class="result"></div>
  
    
<script>
    
    function ajaxcallTofetchpage()
    {
		
       $.ajax({
           type: "GET",
           url: "<%= fetchJsp %>",
