Briefly describe the JavaScript Form submission method (Using JavaScript Submit Form), Using criptusing

I recently encountered the problem of submitting forms using Javascript in my project. I have done it several times before, but it is not comprehensive enough. I have summarized several methods of submitting forms using JavaScript and compared them, select a method that best fits the project.

I am currently working on a small User Creation System for Sun Communication Suite. We all know that we can access the server through forms, Ajax and links. The simplest way is to use connections, for example: <a href = UserServlet? Event = SEARCH_MAILING_LIST & currentPage = 1 & keyword = "+ keyword +" & searchBy = "+ searchBy +" & cn = "+ request. getAttribute ("cn") + "> First Page </a>: writes all the required data to the hyperlink. If you can observe it, you will know, in the above link, only currentPage is changed. Other parameters such as event, keyword, searbyBy, and cn are unchanged, then I thought that if I could encapsulate these unchanged parameters in a form, I would use JavaScript to submit the form when the user clicks the hyperlink above, then I will naturally access the server.

Form:

<form name="pagination" id="pagination" action="UserServlet" method="get"><input type="hidden" name="currentPage" value="1"/><Input type="hidden" name="cn" value="<%=request.getAttribute("cn")%>"/><input type="hidden" name="keyword" value="<%=request.getAttribute("keyword")%>"/><input type="hidden" name="searchBy" value="<%=request.getAttribute("searchBy")%>"/><input type="hidden" name="event" value="SEARCH_USER_FOR_MAILING_LIST"></form>

During the form submission process, I only need to pass the currentPage parameter to JavaScript, so I changed the above connection to the following form:

<a href=# onclick=document.pagination.currentPage.value="+pages[j]+";document.pagination.submit();><span style='color: red;'>["+pages[j]+"]</span></a>

You must note that the document. pagination. currentPage. value = "+ pages [j] +"; written in document. pagination. submit ();, so that before the user submits the form, the parameter currentPage has been changed to the value we need. In this way, I have used the connection to submit the form, but I have encountered a problem. I need to try the above Code on many pages. If I can write a piece of JavaScript in a unified way, I will maintain the entire system in the future, so I have written a JavaScript function.

function submitForm(id,currentPage){//var currentPage = document.pagination.currentPage.value;//alert(currentPage);//currentPage=100;//var currentPage = document.pagination.currentPage.value;//alert(currentPage);document.pagination.currentPage.value=currentPage;var form = document.getElementById(id);form.submit();}

Then I will use this function on the superjoin onclick event:

<A href = # onclick = submitForm ('pagination', "+ pages [j] +")> ["+ pages [j] +"] </a>, you can see that the entire code segment is much simpler.

So I summarized it and usedThere are two ways to write a Javascript submission form:(Based on my current understanding)

1. document. formName. submit ();

2. var form = document. getElementById (id );

Form. submit ();

Next time I want to share with you how to implement paging using JNDI. I have attached the code below for your reference.

Commons. js

function submitForm(id,currentPage){//var currentPage = document.pagination.currentPage.value;//alert(currentPage);//currentPage=100;//var currentPage = document.pagination.currentPage.value;//alert(currentPage);document.pagination.currentPage.value=currentPage;var form = document.getElementById(id);form.submit();}
