encounter a complex problem
I am the front end and I am currently working with the back end
js I have no problem testing on my own machine
but as soon as the backend is moved to our backend
the js and jquery I wrote about a lot of problems sometimes run and sometimes they don"t
it"s very strange that some js don"t even run at all
my guess is that the background environment is too complex (at least 10 years old system, and a lot of jquery suites are installed), which makes it easy to conflict
.I would like to ask if there is any solution to this situation
in addition, I find that if I use a href= "https://www.dropzonejs.com/-sharpinstallation)" rel=" nofollow noreferrer "> https://www.dropzonejs.com/-sharpi., I can be very stable and must be able to run
.but the js you wrote won"t move? ?
I don"t know what the problem is
mainly because this section of js will not run
$(".form-img-wrap").on("change", ".upload", function() {
var _this = this;
$.filePreview.create(this, {
isReader: false,
progress: function(key, percent) {
console.log(percent)
},
success: function(key, obj) {
var $img = $(_this).parents(".form-img-wrap").find(".img").eq(key);
$img.css({
"background-image": "url(" + obj.preview + ")"
});
}
});
});
