msg,我得到的回应:(萤火虫)
<span class='userWallComment'>

DETTE ER EN TEST

<div class="clearfloat"></div>
</span>
它正确地发送和执行ajax调用,它有一些响应,但它没有切换它?
这是div:
<div id="showWallCommentsFor<?php echo $displayWall["id"]; ?>" style="display: none;">
</div>
答案 0 :(得分:1)
您的if
- else
声明存在缺陷:
if ( $msg.text().length ) {
// ...
} else {
// $msg has a length of ZERO by definition here!!!
$msg.hide().text( msg ).slideToggle(300);
}
第一次触发AJAX调用时#showWallCommentsFor
为空,因此它内部没有.userWallComment
因此,$msg
将不会被定义。
您应该使用以下内容将文字直接添加到else
中的原始div中
if ( $msg.text().length ) {
// ...
} else {
// otherwise just hide it, add the text, and then toggle it in
// You cannot use $msg here, since it has a length of 0.
// Add text directly to the original div instead.
// You do not need to hide the DIV first since it is already
// invisible.
$('#showWallCommentsFor'+wallID).text( msg ).slideToggle(300);
}
最后,在else
中,您无需.hide()
#showWall...
div,因为由于style="display: none;"
,div可能是不可见的。
