So whole code is provided above , here adding instance works fine , but only problem is when i click on delete all the checkbox values selected should be passed to php , so that i can delete that particular row from csv file .
推荐答案
基于您对代码的一些修改注释:第一个-将您所有的javascript函数放在一个位置，可以说在关闭正文标记之前-像这样:
Based on your edit couple of notes about your code: 1st - put all you javascript function in 1 place, lets say just before the closing body tag - like this:
<script>
$(document).ready(function(){
// all your function here ! in 1 place
});
</script>
</body>
</html>
2nd-不是那么重要，但是仍然将所有php代码移到文件顶部:
2nd - not so important but still, move all the php code at the top of your file:
<?php
// all the php here
?>
<!DOCTYPE html>
<html>
<head>
...
...
据我了解，您是在与复选框一起形成的同一页面上发出请求.所以你可以有这样的东西:
As far as I understand you're making request to the same page where you form with check boxes is. So you can have something like this:
<?php
if (isset($_POST['kvcArray'])) {
echo "<pre>";
echo "<b>".__FILE__."</b><br/>";
var_dump(json_decode($_POST['kvcArray'], true));
echo "</pre>";
die();
}
?>
<span class="custom-checkbox"><input type="checkbox" class="checkbox" id="checkbox1" name="options[]" value="1"><label for="checkbox1"></label></span><br />
<span class="custom-checkbox"><input type="checkbox" class="checkbox" id="checkbox2" name="options[]" value="2"><label for="checkbox2"></label></span><br />
<span class="custom-checkbox"><input type="checkbox" class="checkbox" id="checkbox3" name="options[]" value="3"><label for="checkbox3"></label></span><br />
<span class="custom-checkbox"><input type="checkbox" class="checkbox" id="checkbox4" name="options[]" value="4"><label for="checkbox4"></label></span><br />
<input type="submit" class="button" name="insert" value="insert" />
请注意，我已经编辑了您的js代码，构建数组的方式，也无需使用"url"在同一页面上发布时在ajax中显示！
Note that I have edited your js code, the way you're constructing your array and also no need to use "url" inside ajax when posting to same page!
<script type="text/javascript">
$( document ).ready(function() {
$( ".button" ).click(function() {
var val = [];
$("input:checked").each(function (index,value) {
val[index] = this.value;
});
var myJSONText = JSON.stringify(val);
$.ajax({
data: {'kvcArray': myJSONText},
url: 'index.php',
type: 'POST',
success: function(result) {
//alert("Success");
}
});
});
});
</script>
此代码已经过测试，可以100％使用
This code has been tested and works on 100%
