js Dialog removes the X closing function in the upper right corner_javascript skills

When using the dialog pop-up box again, I don't want the X in the upper right corner to close the function, but just display a prompt message.

I found some information online. I found three solutions online: [The first one is available. ]

1.

Copy code The code is as follows:

$(" #div1").dialog({

closeOnEscape:false,

open:function(event,ui){$(".ui-dialog-titlebar-close").hide() ;}

});

I don’t want users to close the pop-up box through the x button provided by jquery dialog. The effect of this method is that unless I provide a close button, there will be no How to close this dialog box.

2. Add dialogClass: "no-close" to dialog --------------- Block the X function in the upper right corner (I have used it but it doesn't work)

3. After finding the dialog pop-up box, find the "x" style and hide it -------$(".ui-log").hide(); (I have used it but it is not good either) use)
