单击任何按钮时，页面URL中的参数都会丢失 [英] Parameters in the page URL are lost when clicking on any button

问题描述

$("#saveNews").click(function() {
                alert("clicked on save");
                alert(idx);
                alert(id);
                alert(type);
                alert(subtype);                 
                window.location = "'"+'news.html?type=' + type +     '&subtype=' + subtype+'&id='+id+"'";
                toSaveNews(idx);
            });

     function toSaveNews(index) {
            alert("inside saving");
            alert(index);
            var newsFD = new FormData($("#fileinfonews"));
            var news = $("#newsDetails").val();
    alert(customer);
    alert("stop");
            newsFD.append("reqData1", reqData1);
            newsFD.append("reqData2", reqData2);
            if (news == "") {
                bootbox.alert("News can't be empty.Enter something."); else {
                alert('b4 ajax');
                $.ajax({
                    type : "POST",
                    url : "/path1/saveNews",
                    data : newsFD,                      

                    processData : false,
                    contentType : false,                        
                    success : function(data) {
                        alert("success!!!!!!!!");

        }

在这里，我甚至在Ajax之前就收到了警报.有3个按钮上载，返回和重置. "savenews"是上传"按钮的ID.在后退按钮中，我输入:

Here I got the alerts even before Ajax. There are 3 buttons Upload, Back and Reset. 'savenews' is the id of Upload button. In back button I put like:

   <button class="btn" id="back" onclick="history.back();">Back</button>

只要我单击这些按钮中的任何一个，URL就会变为 localhost:3338/news.html?

Whenever I click on any of these buttons the URL becomes, localhost:3338/news.html?

我没有任何参数.我不知道为什么你们能给我解决方案吗?谢谢.

I didn't get any parameters. I don't know why. Can you guys please give me the solution?Thanks in advance.

推荐答案

$("#saveNews").click(function(event) {
                                        event.preventDefault();
                                        toSaveNews(idx);
                                    });
                                    //Basically,what the problem is,the form is being submitted automatically.So,prevent that using preventDefault()
