jquery - Reducing code redundancy in a series of javascript function expressions -

i have long series of javascript functions invoked 'onclick' on function name in html.

    corporate number <input type="text" autofocus id="corp_text">     <button onclick="getcorpnum(this.form)">save</button><br><br>      llc number <input type="text" autofocus id="llc_text">     <button onclick="getllcnum(this.form)">save</button><br><br>      type of nonprofit <input type="text" autofocus id="np_text">     <button onclick="getnonprofit(this.form)">save</button><br><br>      other description <input type="text" autofocus id="od_text">     <button onclick="getdesc(this.form)">save</button><br><br> 

in javascript functions similar in form:

    /**      * corporation number text field data.      */      var getcorpnum = function() {          var corp_number = [];          corp_number=document.getelementbyid("corp_text").value;          if (corp_number.length > 0) createjsonobj("corp", corp_number);      }     /**      * llc number text field data.      */     var getllcnum = function() {        var llc_number = [];        llc_number = document.getelementbyid("llc_text").value;        if (llc_number.length > 0) createjsonobj("llc", llc_number);     }      /**      * type of non-profit text field.      */     var getnonprofit=function() {         var np_number = [];         np_number = document.getelementbyid("np_text").value;         if (np_number.length > 0) createjsonobj("np", np_number);     }     /**     * other description text     */     var getdesc=function() {         var getdesc=[];         getdesc = document.getelementbyid("od_text").value;         if (getdesc.length > 0) createjsonobj("other_desc", getdesc);     } 

the issue have other functions these have same form , i'd reduce amount of code. generic capture form of code. difficult me because onclicks need name of of each function object.

you pass in different parts.

corporate number <input type="text" autofocus id="corp_text"> <button onclick="getthing('corp_text', 'corp')">save</button><br><br> 

and use variables in more generic function:

var getthing = function(id, name) {      var values=document.getelementbyid(id).value;      if (values.length > 0) createjsonobj(name, values); } 

but . . . maybe more descriptive "getthing" :)
