Although what is the point to pass 3 parameters to a function that use the parameters to call window.open with the same 3 parameters?

Also do yourself a favour and use

function open_postcode() {
     var postcode = document.getElementById ('WwwCustomerPostcode');
     var ppp = postcode.value;
     var sss = "/www_customers/codeplus/"+ppp;//+postcode.value;//+'/'+property.value;
     var w=window.open(sss,"Spring_Harvest_Holidays","width=780,height=600");
     if (!w) alert('Please allow popups')
     return false; // cancel the link

<a href="/customers/show/2" target="ddd"
onClick="w=window.open(this.href,this.target,'width=300,height=200'); return (w)?false:true">first link</a>

<a href="#" onClick="return open_postcode()">second link</a>

to handle popup blockers and to not unload the page when clicking a link that does not leave the page
