脚本:
<img src="post/images/ex.jpg" />
HTML:
$(document).ready(function() {
var counter = 2;
$("#addButton").click(function() {
if (counter < 2) {
alert("Add more textbox");
return false;
}
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + counter);
newTextBoxDiv.after().html('<label>Textbox #' + counter + ' : </label>' +
'<input type="text" name="textbox' + counter +
'" id="textbox' + counter + '" value="" >' +
'<input type="button" name="button' + counter +
'" id="removeButton' + counter + '" value="Remove Button">');
newTextBoxDiv.appendTo("#TextBoxesGroup");
counter++;
});
$("#removeButton").click(function() {
$("#TextBoxDiv" + counter).remove();
if (counter == 2) {
alert("No more textbox to remove");
return false;
}
});
});
</script>
我需要让删除按钮正常运行。当我按下侧面的相应按钮时,只有它旁边的文本框才能删除。

你遗漏了一些基本的东西。 这是一个可能的解决方案:
$(document).ready(function() {
var counter = 2;
$("#addButton").click(function() {
if (counter < 2) {
alert("Add more textbox");
return false;
}
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + counter).attr("class", 'TextBoxDiv');
newTextBoxDiv.after().html('<label>Textbox #' + counter + ' : </label>' +
'<input type="text" name="textbox' + counter +
'" id="textbox' + counter + '" value="" >' +
'<input type="button" name="button' + counter +
'" class="removeButton" value="Remove Button">');
newTextBoxDiv.appendTo("#TextBoxesGroup");
counter++;
});
$("body").on("click", ".removeButton", function() {
if (counter <= 2) {
alert("No more textbox to remove");
return false;
}
$(this).closest('.TextBoxDiv').remove();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='TextBoxesGroup'>
<div id="TextBoxDiv1">
<label>Textbox #1 : </label>
<input type='textbox' id='textbox1'>
<input type='button' value='Remove Button' class='removeButton'>
</div>
</div>
<input type='button' value='Add Button' id='addButton'>

请尝试此代码,我希望这会对您有所帮助
$(document).ready(function() {
var counter = 2;
$("#addButton").click(function() {
if (counter < 2) {
alert("Add more textbox");
return false;
}
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + counter);
newTextBoxDiv.after().html('<label>Textbox #' + counter + ' : </label>' +
'<input type="text" name="textbox' + counter +
'" id="textbox' + counter + '" value="" >' +
'<input type="button" class="remove" name="button' + counter +
'" id="removeButton' + counter + '" value="Remove Button" onclick="remove(this)">');
newTextBoxDiv.appendTo("#TextBoxesGroup");
counter++;
});
});
function remove(obj)
{
var id =$(obj).attr('id');
var counter =id.replace(/[^0-9]/g, '');
$("#TextBoxDiv" + counter).remove();
if (counter == 2) {
alert("No more textbox to remove");
return false;
}
}
这是html代码
<div id='TextBoxesGroup'>
<div id="TextBoxDiv1">
<label>Textbox #1 : </label>
<input type='textbox' id='textbox1'>
<input type='button' class="remove" value='Remove Button' onclick="remove(this)" id='removeButton1'>
</div>
</div>
<input type='button' value='Add Button' id='addButton'>
