我有以下 Jquery 代码,它会提醒此变量中 HTML 字段的值$(".attachmentsUpload input.file").val());
我的问题是我想像这样将此值传递给变量 val
window.open("http://abc.com/crop/test.php?val="+$(".attachmentsUpload input.file").val()),"_blank","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400");
但它没有传递价值。
<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js'></script>
<script type='text/javascript'>//<![CDATA[
$(function(){
$(".attachmentsUpload input.file").live("change", function () {
if ($(".attachmentsUpload input.file").val() == "") {
return;
}
// your ajax submit
alert("submit value of the file input field=" + $(".attachmentsUpload input.file").val());
$(".attachmentsUpload input.file").replaceWith('<input type="file" class="file" name="file" />');
});
});//]]>
window.open("http://abc.com/crop/test.php?val="+$(".attachmentsUpload input.file").val()),"_blank","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400");
</script>
