当我在我的网站中打开模态时，整个模态会在我放入的两个标签中同时滚动自己的底部。 我试图用'overflow：hidden'禁用身体滚动，但它不起作用。 如果我调整窗口大小，冻结消失但当我滚动模态时，问题再次出现。
我使用jquery / ajax脚本动态加载图像。 可能是这个问题？模态javascript和我的jquery之间的冲突？
在Form标签的这个提取中，我调用模态，移动模态div 在调用之外的形式，因为它将工作，我有 模态内的图像形式输入。当我关闭模态时，它会移动 在表格内再次
<div class="form-group" id="ProgramImage">
<label class="col-sm-3 control-label">Main Image</label>
<?php echo $this->element('common/tooltip',array('message' => 'We need to put in file sizes and image sizes here','title' => 'Image Upload')); ?>
<div class="col-sm-8">
<a href="javascript:;" onclick="put_out();jQuery('#modal-1').modal('show');">
<?php
if(file_exists('./img/'.$this->request->data['Program']['image_url']) && !empty($this->request->data['Program']['image_url'] ) ) {
echo $this->Html->image( $this->request->data['Program']['image_url'].'?'.$timestamp,array('id' => 'image_url_preview','style'=>'max-height: 200px') );
} else {
echo $this->Html->image('placehold_640x300.gif',array('id' => 'image_url_preview','style'=>'max-height: 200px') );
}
?>
</a>
<br /><br />
<a href="javascript:;" onclick="put_out();jQuery('#modal-1').modal('show');" class="btn btn-blue">Choose</a>
</div>
</div>
这是模态代码

最后，我调用的JS代码移动我的模态，加载图像（使用ajax），选择图像等。
$('#tabs a').click(function (e) {
e.preventDefault();
$(this).tab('show');
});
function preview(){
if ($("input[name='data[Program][image_library]']").val() == '')
var url = $("[id='croppedImagePre']").attr('src');
else
var url = '../../'+$("input[name='data[Program][image_library]']").val();
$("[id='image_url_preview']").attr('src',url);
}
function upload(){
$("input[name='data[Program][image_library]']").val('');
}
function library(){
$result = [];
$.ajax({
url : '../images_ajax',
type: 'POST',
async: false,
//data: {branch_id:branch_id,namespace:namespace}, img-thumbnail
success : function(response){
//console.log(response);
result = response;
}
});
var full_obj = JSON.parse(result);
var directory = full_obj.directory;
var url = full_obj.url;
var size = full_obj.size;
var html = '';
for(var i = 0; i < size; i++){
html +='<div class="col-sm-2 col-xs-4" data-tag="1d"><article class="image-thumb "><a href="javascript:;" onclick="select_this(\'image_'+i+'\',\''+size+'\',\''+directory+url[i]+'\')" class="image"><img id="image_'+i+'" src="../../'+directory+url[i]+'"></a></article></div>';
}
$("#library_list").html(html);
}
function select_this(id,size,url){
for (var i = 0; i < size; i++) {
if ( ('image_'+i == id) && !($("#image_"+i).hasClass('img_selected')) ){
$("#image_"+i).addClass('img_selected');
$("input[name='data[Program][image_library]']").val(url);
}else
if( ('image_'+i != id) && $("#image_"+i).hasClass('img_selected') )
$("#image_"+i).removeClass('img_selected');
};
}
function delete_choose(){
upload();
$("input[name='data[Program][image_url]']").val('') ;
}
function put_in(){
$("#modal-1").appendTo("#ProgramImage");
}
function put_out(){
$("#modal-1").prependTo("body");
}
答案 0 :(得分：0)
我刚发现这是一个Z-INDEX问题：我把它设置为10000，我的模态工作正常！
