<html><head><meta charset="utf-8"><title>动态创建按钮</title><script src='http://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js'></script></head><body><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" id="AddMoreFileBox" class="btn btn-info">添加更多的input输入框</a></span></p><div id="InputsWrapper"><div><input type="text" name="mytext[]" id="field_1" value="Text 1"/><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="removeclass"><input type='button' value='删除'></a></div></div><script>$(document).ready(function() {var MaxInputs    = 8; //maximum input boxes allowedvar InputsWrapper  = $("#InputsWrapper"); //Input boxes wrapper IDvar AddButton    = $("#AddMoreFileBox"); //Add button IDvar x = InputsWrapper.length; //initlal text box countvar FieldCount=1; //to keep track of text box added$(AddButton).click(function (e) //on add input button click{    if(x <= MaxInputs) //max input box allowed    {      FieldCount++; //text box added increment      //add input box      $(InputsWrapper).append('<div><input type="text" name="mytext[]" id="field_'+ FieldCount +'" value="Text '+ FieldCount +'"/><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="removeclass"><input type="button" value="删除"></a></div>');      x++; //text box increment    }return false;});$("body").on("click",".removeclass", function(e){ //user click on remove text    if( x > 1 ) {        $(this).parent('div').remove(); //remove text box        x--; //decrement textbox    }return false;})});</script></body></html>
