Javascript on how to stop all link target=_blank

Some discussion here: http://stackoverflow.com/questions/10098898/jquery-javascript-remove-all-target-blank

did not work. Someone else wrote this js.

$(function(){ window.el = { count : 0, clicked : false } var rpSubCat = '.mkt-rp-subcategories' $('.relatedPromo .grid-item').each(function(index){ var relatedPromo = $(this).parents('.relatedPromo') if(index===0){ relatedPromo.addClass('mkt-rp-parentcat') relatedPromo.append($(rpSubCat).css({'top' : -Math.abs($(rpSubCat).outerHeight()+3)})) } var newContent = $(this).find('a').html() $(this).find('a').replaceWith('<div style="cursor:pointer" href="'+$(this).find('a').attr('href')+'">'+newContent+'</div>') $(this).on({ click : function(e){ e.preventDefault(); if(window.el.clicked==true || el.count==0){ window.el.clicked = false; window.el.count++ var subcategories = relatedPromo.children(rpSubCat), gi = subcategories.children('div[grid-item='+(index+1)+']') subcategories.children('.grid-item').hide() if(gi.length===1){ gi.show() $(rpSubCat).css({ 'top' : -Math.abs($(rpSubCat).outerHeight()+3) }) setTimeout(function(){ relatedPromo.find('h2,.product-container-grid').css('visibility','hidden') },400) relatedPromo.animate({ 'height':$(rpSubCat).outerHeight()+5 }) $(rpSubCat).animate({ 'top' : '+='+($(rpSubCat).outerHeight()+5) },function(){ window.el.clicked = true }) }else{ window.location.href = $(this).find('div').attr('href') } } } }) }) $('.mkt-rp-subcategories').each(function(){ $(this).find('.link').on({ click : function(){ window.open($(this).attr('href')) } }) $(this).find('p').on({ click : function(){ window.open($(this).prev().attr('href')) } }) }).append( $('<div/>').attr('class','collapse').append( $('<span/>').attr('class','text').text('Hide / Collapse') ).on({ click : function(){ $('.mkt-rp-parentcat').find('h2,.product-container-grid').css('visibility','visible') $('.mkt-rp-parentcat').animate({ 'height':$('.product-container-grid').outerHeight()+5 }) $(rpSubCat).animate({ 'top' : '-='+($(rpSubCat).outerHeight()+5) }) } }) ) })

When I click on the link I the main page and a undefined black page it's under this page http://www.medline.com/clinical-solutions/falls-management at the bottom
