You could do something like this in a loop based on the number of text fields they enter       lt input  gt    attr  type  text  name  text  i   appendTo   myform      But for better performance I d create all the html first and inject it into the DOM only once   var count   20  var html       while count--      html push   lt input type  text  name  name   count     gt           myform   append html join         Edit this example uses jQuery to append the html  but you could easily modify it to use innerHTML as well

Using Javascript  all you need is document createElement and setAttribute   var input   document createElement  input    input setAttribute  type    text      Then you can use appendChild to append the created element to the desired parent element   var parent   document getElementById  parentDiv    parent appendChild input

The core idea of the solution is   create a new input element Add the type text append the element to the DOM  This can be done via this simple script  var input   document createElement  input    input setAttribute  type    text    document getElementById  parent   appendChild input    Now the question is  how to render this process dynamic  As stated in the question  there is another input where the user insert the number of input to generate  This can be done as follows   x000D   x000D  function renderInputs el     var n   el value  amp  amp  parseInt el value  10     if isNaN n        return           var input    var parent   document getElementById  parent         cleanDiv parent     for var i 0  i lt n  i         input   document createElement  input        input setAttribute  type    text        parent appendChild input          function cleanDiv div     div innerHTML         x000D  Insert number of input to generate   lt  br gt   lt input type  text  onchange  renderInputs this    gt    lt div id  parent  gt  Generated inputs   lt  div gt  x000D   x000D   x000D   but usually adding just an input is not really usefull  it would be better to add a name to the input  so that it can be easily sent as a form  This snippet add also a name   x000D   x000D  function renderInputs el     var n   el value    var input  label    var parent   document getElementById  parent      cleanDiv parent        el value split      forEach function name       input   document createElement  input        input setAttribute  type    text        input setAttribute  name   name       label   document createElement  label        label setAttribute  for   name       label innerText   name      parent appendChild label       parent appendChild input       parent appendChild document createElement  br              function cleanDiv div     div innerHTML         x000D  Insert the names  separated by comma  of the inputs to generate   lt  br gt   lt input type  text  onchange  renderInputs this    gt   lt br gt  Generated inputs   lt  br gt   lt div id  parent  gt    lt  div gt  x000D   x000D   x000D
