下面是代码:

HTML:

<div class="input_fields_wrap">
<button class="add_field_button">Add More Fields</button>
<div>
    <input type="text" name="mytext[]" placeholder="Account Title">
    <input type="text" name="mytext2[]" placeholder="Description">
    <input type="text" name="mytext3[]" placeholder="Credit">
    <input type="text" name="mytext4[]" placeholder="Debit">
</div>
</div>

脚本:

<script type="text/javascript">
$(document).ready(function() {
    var max_fields      = 10; //maximum input boxes allowed
    var wrapper         = $(".input_fields_wrap"); //Fields wrapper
    var add_button      = $(".add_field_button"); //Add button ID

    var x = 1; //initlal text box count
    $(add_button).click(function(e){ //on add input button click
        e.preventDefault();
        if(x < max_fields){ //max input box allowed
            x++; //text box increment
            $(wrapper).append('<div><input type="text" name="mytext[]" placeholder="Account Title"><input type="text" name="mytext2[]" placeholder="Description"><input type="text" name="mytext3[]" placeholder="Credit"><input type="text" name="mytext4[]" placeholder="Debit"><a href="#" class="remove_field">Remove</a></div>'); //add input box
        }
    });

    $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
        e.preventDefault(); $(this).parent('div').remove(); x--;
    })
});

</script>

您只需要更改输入字段的名称.希望对您有所帮助.

You just have to change the name of the input field. I hope it helps.
