Question

I am using Solr’s JSON output for AJAX example as a basis for my project. However I have modified things by adding a drop-down menu in the form and added faceting to the params.

Params:

function getstandardargs() {
    var params = [
        'wt=json'
        ,'facet=true'
        ,'facet.field=brand1'
        ,'facet.field=brand2'
        ,'facet.field=brand3'
        ,'facet.field=brand4'
        ,'facet.limit=2'
        ]; 

Drop- down menu:

<form name="f1" onsubmit='xmlhttpPost("/solr/select"); return false;'>
  <p>query: <input name="query" type="text">  
  <select id="Entity">
  <option value="brand1">Universal</option>
  <option value="brand2">Paramount</option>
  <option value="brand3">Fox</option>
  <option value="brand4">Sony</option>
</select> 
  <input value="Go" type="submit"></p>

I am trying to add the drop-down value to my facet query result as such:

var rsp = eval("("+str+")");
var c=document.getElementById("Entity");
cat=c.options[c.selectedIndex].value;
var output=rsp.facet_counts.facet_fields;
html += "Entity: " + output+'.'+cat;

My facet response sends back: Entity: [object Object].Universal. How do I add the drop-down value to the response query correctly so Solr can actually return the proper facet values? Many thanks.

Answer 1

you will undoubtedly reduce the complexity of this problem by using a library for your ajax request because:

• you can easily do the dom manipulation required to turn them into
  select options
• you can send the request arbitrarily with the expectation to get back an actual json object
• you can avoid the use of eval

And since you said your response is “Entity: [object Object].Universal”, can you try to use console.log( output ); to tell us what is returned in the object, officially? there’s a possibility that by concatenating strings with an object, you’re messing up the output object

if it is in fact an object, you can access it iteratively like this:

for(var x in rsp.facet_counts.facet_fields) {
    //rsp.facet_counts.facet_fields[x]
}
