Introduction to the functions and usage examples of RadioButtonList in jQuery_jquery

Code analysis

Copy code The code is as follows:

$ ("#<%= ibSubmit.ClientID%>").click(function() {
var flag = true;
//alert($("table[id^=ctl]"). length);
//Create a checked arr array to store the checked status of each radiobutton
var arr = new Array;
$("table[id^=ctl] input[type= radio]").each(function(i) {
arr.push(this.checked);
});

//Then create an arrTrue array to filter false arr array

var arrTrue = new Array;
$.each(arr, function(i) {
if (arr[i] == true) {
arrTrue.push(arr [i]);
}
});

//Of course, you can also use the grep function to simplify the filtering arr array operation

//arr = $.grep( arr, function(n, i) {
//return n == true;
//});

var groupLen = Math.floor($("table[id^=ctl ]").length 1 / 3);

//Finally, let’s be simple, just judge whether the length of arrTrue is 11.

//Because there are 33 radiobuttons in total , each group is a group of 3, and the rule is to choose 1 out of 3 in a group, //so all 11 radiobuttons must be selected.
if (arrTrue.length != groupLen) {
flag = false. ;
}
return false;

});

Full code

Copy code The code is as follows:

$(function() {
$("#<%= ibSubmit.ClientID%>") .click(function() {
var flag = true;
var arr = new Array;
$("table[id^=ctl] input[type=radio]").each(function( i) {
arr.push(this.checked);
});
arr = $.grep(arr, function(n) {
return n == true;
} );
var groupLen = Math.floor($("table[id^=ctl]").length 1 / 3);
if (arr.length != groupLen) {
flag = false ;
}
return false;
});
});

Finally, the code to generate Table is attached: (two generation methods, JQuery version, C# version ) – (can be viewed or not)

jQuery version

Copy code The code is as follows :

var array = ["XXXX",""XXXX","XXX"];
$.each(array, function(i) {
table.append(" "
""
"< ;/td>");
});
