title: How to replace all single characters except the first
body: <p>I need to replace all single characters except the first.
  Because I working with the server that I programmed in Python.
  The information I passing always on Url.
  The Url is:</p>
  
  <pre><code>http://localhost:8100/index2?decode=demo_title=Demo+title&amp;proc1_script=script.sh+parameters&amp;inputp3_id=pepepe&amp;outputp2_value=&amp;demo_input_description=hola+mundo&amp;outputp4_visible=on&amp;inputdata1_max_pixels=1024000&amp;inputdata1_image_depth=1x8i&amp;tag=&amp;outputp1_id=nanana&amp;proc1_src_compresion=zip&amp;outputp3_description=&amp;inputp1_type=text&amp;inputdata1_description=input+data+description&amp;inputp2_description=bien%3F&amp;inputp3_description=funciona&amp;outputp3_type=header&amp;outputp2_visible=on&amp;outputp3_visible=on&amp;outputp1_type=header&amp;outputp3_value=&amp;demo_params_description=va+bien&amp;demo_result_description=win%3F&amp;outputp1_description=&amp;inputdata1_type=image2d&amp;inputp1_value=si&amp;proc1_chk_script=off&amp;outputp4_info=&amp;outputp2_id=nanfdsvfa&amp;inputp1_description=funciona&amp;demo_wait_description=boh&amp;outputp4_description=&amp;inputp2_id=papapa&amp;inputdata1_id=id_lsd&amp;inputp1_visible=on&amp;proc1_chk_cmake=off&amp;proc1_cmake=-D+CMAKE_BUILD_TYPE%3Astring%3DRelease+&amp;inputp3_visible=+off&amp;outputp1_visible=on&amp;outputp1_value=&amp;outputp4_value=&amp;inputp2_visible=on&amp;proc1_source=lsd-1.5.zip&amp;inputp3_value=si&amp;proc1_make=-j4+-C+&amp;images_config_file=cfgmydemo.cfg&amp;outputp2_type=header&amp;proc1_subdir=xxx-1.5&amp;proc1_chk_make=on&amp;inputp1_id=popopo&amp;proc1_url=http%3A%2F%2Fwww.ipol.im%2Fpub%2Falgo%2F...&amp;inputp2_value=no&amp;demo_data_filename=data_saved.cfg&amp;inputdata1_info=info_lsd&amp;outputp3_info=&amp;inputdata1_image_format=.pgm&amp;inputdata1_compress=False&amp;outputp1_info=&amp;outputp3_id=nananartrtrt&amp;inputp2_type=integer&amp;proc1_id=lsd&amp;inputp3_type=float&amp;outputp2_description=&amp;outputp4_type=header&amp;outputp2_info=&amp;outputp4_id=nana&amp;tag=&amp;inputp4_id=popopo&amp;inputp4_type=text&amp;inputp4_description=cddc&amp;inputp4_value=sdlk&amp;inputp4_info=dsl

  <p>Now I have this problem that the first character is important on URL and not have to replace.</p>
  
  <p>This is my script for replace all characters in Javascript:</p>
  
  <pre><code>var $fm = $("#formparam");
                  $.get($fm.attr('${nextstep}'))
                      .done(function(data, ok){
                      var fr=$fm.serialize();
                      fr=fr.replace(/\&amp;/g,"+%23+");
                      fr=fr.replace(/\=/g,"%24+");
                      alert('call done: ' +fr);
                      // data is the content of the response
                      document.location.href+="index2?"+fr})
                      .fail(function(data){
                      alert('call failed');
                      // call failed for some reason -- add error messaging?
                      });
  </code></pre>
  
  <p>And How to change the script for not replace the first = ?</p>
