在jqgrid中验证失败时突出显示错误单元格或输入

Question

我正在使用jqgrid内联编辑,并使用编辑规则在网格中进行验证.我想添加类来突出显示错误的错误(例如:ui-state-error),验证失败.我可以设置类来突出显示错误

jQuery('#'+ grid_id).jqGrid('setCell',row_id,errfields [a],'','ui-state-error',{color:'blue'});

但是当内置验证失败时,它无法在jqgrid中运行.如何突出显示验证错误触发的单元格/输入.

Answer 1

该演示展示了如何解决问题:

在演示中,"Amount","Tax"和"Total"列将使用以下验证规则进行验证:

editrules:{required:true,number:true}

在任何验证错误上,将添加验证失败的第一个输入字段dditional class"ui-state-error".它是标准的jQuery UI CSS类.Addionally我将焦点设置到输入字段.

对于实现,我覆盖(链)方法的默认实现$.jgrid.checkValues和$.jgrid.hideModal.这是相应的代码:

var grid = $("#list");
grid.jqGrid({
    // define all jqGrid options
});

var originalCheckValues = $.jgrid.checkValues,
    originalHideModal = $.jgrid.hideModal,
    iColWithError = 0;
$.jgrid.checkValues = function(val, valref,g, customobject, nam) {
    var tr,td,
        ret = originalCheckValues.call(this,val, valref,g, customobject, nam);
    if (!ret[0]) {
        tr = g.rows.namedItem(editingRowId);
        if (tr) {
            $(tr).children('td').children('input.editable[type="text"]').removeClass("ui-state-error");
            iColWithError = valref; // save to set later the focus
            //error_td_input_selector = 'tr#'+editingRowId+' > td:nth-child('+(valref+1)+') > input.editable[type="text"]:first';
            td = tr.cells[valref];
            if (td) {
                $(td).find('input.editable[type="text"]').addClass("ui-state-error");
            }
        }
    }
    return ret;
};
$.jgrid.hideModal = function (selector,o) {
    var input, oldOnClose, td,
        tr = grid[0].rows.namedItem(editingRowId);
    if (tr) {
        td = tr.cells[iColWithError];
        if (td) {
            input = $(td).children('input.editable[type="text"]:first');
            if (input.length > 0) {
                oldOnClose = o.onClose;
                o.onClose = function(s) {
                    if ($.isFunction(oldOnClose)) {
                        oldOnClose.call(s);
                    }
                    setTimeout(function(){
                        input.focus();
                    },100);
                };
            }
        }
    }
    originalHideModal.call(this,selector,o);
};
