常用的js 总结

1、点击一个按钮，跳转到新页面

$("#btnCancel").click(function(){
            location.href="${ctx}/engine/formula/";
        });

2、使用jquery Validate 验证后，运算ajax 进行计算

$("#btnCalculate").click(function(){
            if($("#inputForm").valid())
            {
                $.ajax({
                    type : "post",
                    async : false,
                    url : "${ctx}/engine/formula/cal",
                    data : $("#inputForm").serialize(),
                    success : function(data) {
                        $("#formulaResult").val(data);
                    },
                    error : function(XMLHttpRequest, textStatus) {
                        alert(XMLHttpRequest.status + ","
                                + XMLHttpRequest.readyState + ",error="
                                + textStatus);
                    }
                });
            }
        }); 

3、使用select2 来表示select，并且选中默认值（useJob_hidden）,若是值为y 的话，就显示 jobDiv，否则隐藏

//所有下拉框使用select2
$("select[multiple!='multiple']").select2();
 
var jobDivShow = function(type)
{
    if(type == 'y' ||type == 'Y' )
    {
        $("#jobDiv").show();
        var status = $("#jobStatus_hidden").val();
        if (status) {
            $("#jobStatus").select2("val", status);
        }                   
    }
    else
    {
        $("#jobDiv").hide();
    }
};
var objtype = $("#useJob_hidden").val();
if(objtype)
{
    $("#useJob").select2("val", objtype);
    jobDivShow(objtype);
}
$("#useJob").change(function(){
    var type = $(this).children('option:selected').val();
    jobDivShow(type);
});
