EasyUI项目中的自定义JS

自定义方法：

(function($) {
        $.extend($, {
            //获取下标，删除时使用
        getArrayIndex :  function (array,value) {
            var index = -1;
            var length = array.length;
            for (var i = 0; i < length; i++) {
                if (array[i].id == value.id) {
                    index = i;
                    break;
                }
            }
            return index;
        } ,
        removeValue : function (array,value){
            var index = $.getArrayIndex(array,value);
            if(index < 0) return array;
            array.splice(index,1);
            return array;
        }
        });
    })(jQuery);


    function checkExist(array,node){
        var id = node.id;
        var flag = false;
        for(var i = 0;i<array.length; i++){
            var row = array[i];
            if(row.id == id){
                flag = true;
                break; //中断循环
            }
        }
        return flag;
    }


    Array.prototype.getIndexByValue= function(value)
    {
        var index = -1;
        for (var i = 0; i < this.length; i++)
        {
            if (this[i] == value)
            {
                index = i;
                break;
            }
        }
        return index;
    };

    //在数组中获取指定值的元素索引
    Array.prototype.removeValue= function(value)
    {
        var index = this.getIndexByValue(value);
        var s = this.splice(index,1);
        return s;
    }  ;

String.prototype.startsWith = function (substring) {
        var reg = new RegExp("^" + substring);
        return reg.test(this);
        };

        String.prototype.endsWith = function (substring) {
        var reg = new RegExp(substring + "$");
        return reg.test(this);
        };

        String.prototype.trim = function(){
        var reg = /[s

]+/g;
        return this.replace(reg, "");
        }

/**
     * 序列化元素，返回JSON对象
     * 参数：flag 空元素是否系列化成空字符串
     */
    $.fn.toJson = function (flag) {
        var json = {};
        var fields = this.serializeArray();
        $.each(fields, function () {
        if (json[this.name]) {
            if (!json[this.name].push) {
            json[this.name] = [json[this.name]];
            }
            if (flag || (!flag && this.value != "")) {
            json[this.name].push(this.value || "");
            }
        } else {
            if (flag || (!flag && this.value != "")) {
            json[this.name] = this.value || "";
            }
        }
        });
        return json;
    };

其他优化方法：

    function comboboxInit(obj,lookupType,form,defaultValue,wid){
        var _obj = $('#'+obj);
        if('' != form  && typeof form != 'undefined'){
            _obj = $("#"+form).find("#"+obj);
        }
        if('' == wid || typeof wid == 'undefined'){
            wid = "150";
        }
        _obj.combobox({
            required:true,
            wid,
            valuefield:'value',
            textField:'text',
            panelHeight:'auto',
            url: root + 'esbService/lookupValComBox.json?lookupType='+lookupType,
            editable:false,
            onLoadSuccess:function(){
                if('' != defaultValue  && typeof defaultValue != 'undefined'){
                    _obj.combobox('select',defaultValue);
                }else{
                    _obj.combobox('select','');
                }
            }
        });
    }


    function toggleSenior(but) {
        var check = false;
        if ($(but).attr("checked") == "checked") {
            check = true;
        }
        var rowHeight = 0;
        $(but).parents("form:first").find("tr.advancedCondiction").each(
            function (i, n) {
                rowHeight += 28;
                if (check) {$(n).show();}
                else {$(n).hide();}
            });
        var $layout = $(but).parents(".easyui-layout:first");
        var panelHeight = $layout.layout("panel", "north").panel("options").height;
        if (check) {
            panelHeight += rowHeight;
        } else {
            panelHeight -= rowHeight;
        }
        $layout.layout("panel", "north").panel("resize", {height: panelHeight});
        $layout.layout("resize");
        if(!check){
            clearAdvanced();
        }
    }


    function doSearch(form){
        var $fm = $(form);
        var fields =$('#queryForm').serializeArray();
        var params = $fm.datagrid('options').queryParams;
        $.each( fields, function(i, field){
            params[field.name] = field.value;
        });
        $fm.datagrid('reload');
    }

    function resetBtn(formId){
        $(formId).find("input[type='text']").each(function(){
            $(this).val("");
        });
        $('#method').combobox('select','');

        if($('#applicationId').length > 0){
            $('#applicationId').combobox('select','');
        }
    }


日期：
1、
    formatter:function(val,rec){
                    return formattime(val);
                }

    function formattime(val) {
        var date = new Date(val);
        var tmp = trimDate(date.getFullYear())
            + '-' + trimDate(date.getMonth() + 1)
            + '-' + trimDate(date.getDate())
            + " "+trimDate(date.getHours())
            + ":"+trimDate(date.getMinutes())
            + ":"+trimDate(date.getSeconds());
        return tmp;
    }

    function trimDate(tmp){
        return parseInt(tmp) < 10 ? "0"+tmp : tmp;
    }

/**

public class JsonDateSerializer extends JsonSerializer<Date> {
    private static DateFormat dateFormat = new SimpleDateFormat(
            "yyyy-MM-dd HH:mm:ss");
