jquery无刷新添加和删除input输入框 增加减少input框

一、页面代码

<a href="#" 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="#" class="removeclass">×</a></div>
</div>

二、脚本

<script>
$(document).ready(function() {

var MaxInputs = 8; //maximum input boxes allowed
var InputsWrapper = $("#InputsWrapper"); //Input boxes wrapper ID
var AddButton = $("#AddMoreFileBox"); //Add button ID

var x = InputsWrapper.length; //initlal text box count
var 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="#" class="removeclass">×</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>
