我一直在使用模式弹出窗口,在该窗口中显示图像并在图像上做标签。模态效果很好,并且图像显示完美,但是我面临的问题是,当我借助按钮关闭模态时,即使关闭模态后,模态背景也会逐渐消失在主窗口中。
我已附上以下代码:
HTML :(情态)
<div id="myModal" class="modal">
<!-- The Close Button -->
<span class="close">×</span>
<!-- Modal Content (The Image) -->
<div id="imagearea" class="imagearea">
<img class="modal-content" id="img01">
</div>
<div class="text_container">
<br>
<div class="input_tag">
<span class="right_sec_text">Select a region from the picture</span>
<div class="tags">
</div>
<div class="input_box">
<input type="text" name="tags" class="input_textbox">
<button id="settag" class="btn_settag">Set Tag</button>
</div>
<div class="footer_btn">
<p><button class="btn_success">Confirm Selection</button>
<p><button class="btn_cancel" >Cancel</button>
</div>
</div>
</div>
</div>
Javascript :(用于模式和图像上方的框)
var modal = document.getElementById("myModal");
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById("imgside");
var modalImg = document.getElementById("img01");
img.onload = function(){
modal.style.display = "block";
modalImg.src = this.src;
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
function preview(img, selection) {
if (!selection.width || !selection.height)
return;
$('#x1').val(selection.x1);
$('#y1').val(selection.y1);
$('#x2').val(selection.x2);
$('#y2').val(selection.y2);
$('#w').val(selection.width);
$('#h').val(selection.height);
$('.img_error').removeClass("error");
}
$(function() {
$('#img01').imgAreaSelect({
handles: true,
fadeSpeed: 200,
onSelectChange: preview
});
});
$(".btn_cancel").click(function(){
$('#myModal').hide();
$('.imagearea').removeClass().removeAttr('style');
$('.modal-backdrop').remove();
});
图片1 :(带有图片的模式)
图片2 :(关闭后为模态)
当尝试单击btn_cancel按钮时,我尝试从模式中删除样式和div,但没有用。有人可以帮我解决这个问题。
答案 0 :(得分:0)
在没有img01但使用引导程序模式的情况下,无法尝试在JSFiddle中进行复制,您应该使用$('#myModal').modal('hide')
隐藏
