Ajax callback to open a new form to prevent browsers from blocking, just do it!

Problem analysis:

Function click_fun () {window.open ("www.baidu.com"); / can open $.ajax ({'url':' ${pageContext.request.contextPath} / activity/savePrizes.htm', 'type':' post', 'dataType':' json', 'data': data, success: function (data) {window.open ("www.baidu.com") / / blocked}, error:function () {}});}

Analysis:

Opening a new form can only be triggered within the click event. Opening the form in the callback function within the click event will be blocked, and the browser will think it is a code such as an advertisement pop-up window.

Solution 1:

Function click_fun_new () {var tempwindow=window.open () / / Open the temporary form first. Since it is triggered within the click event, it will not be blocked by $.ajax ({'url':' ${pageContext.request.contextPath} / activity/savePrizes.htm', 'type':' post', 'dataType':' json', 'data': data, success: function (data) {temp_window.location = "www.baidu.com") / / change the path of the temporary form when callback}, error:function () {tempwindow.close (); / / the callback finds that you can close the previous temporary form}} when you don't need to open the form);}

Solution 2:

Function click_fun_new () {var flag = false; $.ajax ({'url':' ${pageContext.request.contextPath} / activity/savePrizes.htm', 'type':' post', 'dataType':' json', 'data': data,' async':false,// synchronous request success: function (data) {$("# a"). Attr ("href", "www.baidu.com") / / change the href flag = true;// change flag of a tag on the page or created during callback}, error:function () {}}); if (flag) {$("# a") .click () / / simulated click after href property change}} above is all the content of the article "how to implement ajax callback to open a new form to prevent browsers from blocking".
