我想点击添加图标(+)时附加输入框,而如果我们要删除附加的输入框,我们点击删除(X)按钮。但是在这里我希望附加的输入框出现在静态输入框之前,即相反(从下到上)的方向。
Here is the image of what i want to display:
Html:
<div class="input_fields_wrap">
<input type="text" name="mytext[]">
<a href="javascript:void(0);" class="add_field_button" title="Add field"><img src="images/plus.png" /></a>
</div>
代码:
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[]"/><a href="javascript:void(0);" class="remove_field" title="Remove field"><img src="images/close.png"/></a></div>'); //add input box
}
});
$(wrapper).on("click", ".remove_field", function(e) { //user click on remove text
e.preventDefault();
$(this).parent('div').remove();
x--;
});
答案 0 :(得分:1)
使用.prepend()在点击按钮输入之前添加输入请在下面的代码段中找到更多信息
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).prepend('<div><input type="text" name="mytext[]"/><a href="javascript:void(0);" class="remove_field" title="Remove field"><img src="images/close.png"/></a></div>'); //add input box
}
});
$(wrapper).on("click", ".remove_field", function(e) { //user click on remove text
e.preventDefault();
$(this).parent('div').remove();
x--;
});
