多个字段引导动态表单

Question

我试图在bootstrap中创建一个包含多个字段的动态表单，似乎我需要在表单元素中附加一个非常冗长的字符串。我很确定应该有更有效的方法来做到这一点。如果您能告诉我其他方法，我感谢您。

HTML：

<!-- start of the column with properties(form-control)-->
  <div class="col-lg-8" id="property-col">
    <div class="container">
      <form class="form">

      <div class="row">
        <h3>Properties</h3>

JavaScript的：

function getHTMLString() {
    var complex_html = [
        '<div class="row" id="primitive-form">',
            '<div class="form-group form-horizontal">',
              '<div class="container">',
                '<div class="form-inline" id="primitive_fields">',
                  '<select class="input-small form-control" id="primitive-selector" name="PrimitiveChoose[]">',
                    '<option value=" " disabled selected>primitive</option>',
                    '<option value="sphere">sphere</option>',
                    '<option value="triangle">triangle</option>',
                  '</select>',
                  '<input type="number" class="input-small form-control" id="diameter"  name="Diameter[]" step="any" placeholder="diameter(D)">',

    $('#dynamic_form').on("click","#remove_more", function(e){ //user click on remove text
        e.preventDefault(); $(this).parent('div').parent('div').parent('div').parent('div')[0].remove(); formCount--;

    })
});

为您的form-inline另一个课程提供克隆

var formRow = $('.div_to_clone').first();
var clone = formRow.clone();

$('#dynaic_form').append(clone);
