非常感谢任何帮助。
好的。时间结束感谢@Bret给我一个方向。以下是最终工作的代码片段 -
$(#form)。on(submit,function {
if($(#form)。valid()){
var nNodes = oTable.fnGetHiddenTrNodes();
$('td' ,nNodes).each(function(index,ncolumn){
var nHidden = document.createElement('input');
nHidden.type ='hidden';
nHidden .name = $(input,ncolumn).attr(name);
nHidden.value = $(input,ncolumn).val();
if typeof(nHidden.name)!=undefined)
$(#form)。append(nHidden);
nHidden = document.createElement('input');
nHidden.type ='hidden';
nHidden.name = $(textarea,ncolumn).attr(name);
nHidden.valu e = $(textarea,ncolumn).val();
if(typeof(nHidden.name)!=undefined)
$(#form)。append(nHidden);
nHidden = document.createElement('input');
nHidden.type ='hidden';
nHidden.name = $(textarea,ncolumn).attr(name);
nHidden.value = $(textarea,ncolumn).val();
if(typeof(nHidden.name)!=undefined)
$(#form)。append(nHidden);
nHidden = document.createElement('input');
nHidden.type ='hidden';
nHidden.name = $(select,ncolumn).attr(name);
nHidden.value = $(select,ncolumn).attr(value);
if(typeof(nHidden.name)!=undefined)
$(#form)。append(nHidden);
});
clickedSave = true;
} else {
validator.focusInvalid();
返回false;
}
});
谢谢。
I'm stuck with an issue and its eating my time now. I have a table with 7 records (for instance) and this table has input and textarea elements, where a user can type in. Now with pagination having the value as 5 records per page, I have two pages. The user enters data into comments section, clicks on the "next" in the pagination and enters value in the comments section. So technically, the user entered values into both the pages as splitted by datatable pagination logic. The problem is, when the user hits save, its saving only those elements which are on focus, more easy to understand which are visible on the page. I read the API and FAQs, and its clear that datatable hides the elements which are not in focus, making them practically impossible to find in DOM. Below is the code and I need help on how can I get the data from the hidden rows using the fnGetHiddenTrNodes() method, create hidden elements and append them to the existing visible table elements before submitting the form. I tried the below code, but it isn't working.
$("#form").on("submit",function(){
if($("#form").valid()){
var nNodes = oTable.fnGetHiddenTrNodes();
for ( var i=0 ; i<nNodes.length ; i++ )
{
var nHidden = document.createElement( 'input' );
nHidden.type = 'hidden';
nHidden.name = "hidden_input_"+i;
nHidden.value = $('input', nNodes).val();
//alert(nHidden.value);
this.appendChild( nHidden );
}
$("#form").submit();
}else {
validator.focusInvalid();
return false;
}
});
Any help is greatly appreciated.
Alright.! Time to wrap up. Thanks to @Bret for giving me a direction. Below is the code snippet that's finally working -
$("#form").on("submit",function(){
if($("#form").valid()){
var nNodes = oTable.fnGetHiddenTrNodes();
$('td', nNodes).each(function(index,ncolumn) {
var nHidden = document.createElement( 'input' );
nHidden.type = 'hidden';
nHidden.name = $("input", ncolumn).attr("name");
nHidden.value = $("input", ncolumn).val();
if(typeof(nHidden.name) != "undefined")
$("#form").append( nHidden );
nHidden = document.createElement( 'input' );
nHidden.type = 'hidden';
nHidden.name = $("textarea", ncolumn).attr("name");
nHidden.value = $("textarea", ncolumn).val();
if(typeof(nHidden.name) != "undefined")
$("#form").append( nHidden );
nHidden = document.createElement( 'input' );
nHidden.type = 'hidden';
nHidden.name = $("textarea", ncolumn).attr("name");
nHidden.value = $("textarea", ncolumn).val();
if(typeof(nHidden.name) != "undefined")
$("#form").append( nHidden );
nHidden = document.createElement( 'input' );
nHidden.type = 'hidden';
nHidden.name = $("select", ncolumn).attr("name");
nHidden.value = $("select", ncolumn).attr("value");
if(typeof(nHidden.name) != "undefined")
$("#form").append( nHidden );
});
clickedSave = true;
}else {
validator.focusInvalid();
return false;
}
});
Thanks.
