如何将文字Add Your Image
更改为Change Your Image
。
<label class="control-label col-md-offset-4 col-md-4 btn green feedbackImg" style="text-align:center;">
Add Your Image
<input type="file" name="data[Feedback][img]" class="form-control hide single_img_btn" id="1" style="display: none;">
</label>
$('.feedbackImg').text('Change Your Image');
但它改变了label
如下:
<label class="control-label col-md-offset-4 col-md-4 btn green feedbackImg" style="text-align:center;">
Add Your Image
</label>
这意味着它也删除了输入标签。除了文本之外,我怎么能保持一致呢?

如果您可以更改HTML,只需在span
中包含您要更改的文字,以便更轻松地选择:
<label class="control-label col-md-offset-4 col-md-4 btn green feedbackImg" style="text-align:center;">
<span>Add Your Image</span>
<input type="file" name="data[Feedback][img]" class="form-control hide single_img_btn" id="1" style="display: none;">
</label>
$('.feedbackImg span').text('Change Your Image');
如果您无法更改HTML,那么您需要修改JS代码以检索并修改textNode本身:
$('.feedbackImg').contents().first()[0].textContent = 'Change Your Image';

您需要更新textNode
contents()
- 用于获取包含文字和评论的所有节点eq()
- 获取第一个元素,即textNode(label)replaceWith()
- 使用新文字更新文字内容<强> CODE:强>
$('.feedbackImg').contents().eq(0).replaceWith('Change Your Image');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<label class="control-label col-md-offset-4 col-md-4 btn green feedbackImg" style="text-align:center;">
Add Your Image
<input type="file" name="data[Feedback][img]" class="form-control hide single_img_btn" id="1" style="display: none;">
</label>
&#13;
OR
$('.feedbackImg').contents()[0].nodeValue = 'Change Your Image';
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<label class="control-label col-md-offset-4 col-md-4 btn green feedbackImg" style="text-align:center;">
Add Your Image
<input type="file" name="data[Feedback][img]" class="form-control hide single_img_btn" id="1" style="display: none;">
</label>

将html更改为此
$('.image_label').text('Change Your Image');
然后在jquery
- (void)setExtractedImageForTableView:(UIImage *)extractedImage {
self.documentImageView.image = nil;
self.documentImageView = nil;
self.documentImageView = [[UIImageView alloc] initWithImage:extractedImage];
self.documentImageView.contentMode = UIViewContentModeScaleAspectFit;
if (!CGSizeEqualToSize(extractedImage.size, CGSizeZero)) {
self.documentImageView.frame = CGRectMake(CGRectGetMinX(self.view.frame), CGRectGetMinY(self.tableView.frame) + 70, CGRectGetWidth(self.view.frame), (extractedImage.size.height/extractedImage.size.width) * CGRectGetWidth(self.view.frame));
self.segmentedView.frame = self.documentImage.frame;
[self.segmentedView addSubview:self.segment];
[self.segmentedView addSubview:self.documentImageView];
[self.tableView.tableHeaderView addSubview:self.segment];
[self.tableView.tableHeaderView addSubview:self.documentImageView];
CGRect frame = self.documentImageView.frame;
frame.size.height = self.documentImageView.frame.size.height + 100;
self.tableView.frame = CGRectMake(0, 0, 400, 300);
self.tableView.tableHeaderView.frame = frame;
}
}
