随记

做项目遇到的一些小问题，记下来。

封装js类调用

var chartParam ={
containerId:'sq1',
titleText:"",
subtitleText:"",           //无值不出现
subtitleAlign:null,
subtitleX:null,
subtitleY:null,
xAxisLabelsRotation:null,//为null就默认值，水平
xAxisLabelsFontSize:"12px",
yAxisTickInterval:null,    
yAxisTitleText:"亿度",
tooltipUnit:"亿度",
colors: new Array('#009966','#669999','#265430','#b7d275','#75780d','#9933CC','aa8f0e','#FFFFFF'),//颜色数组
type:"spline",
spacingTop:20,
spacingRight:10,
spacingBottom:5,
spacingLeft:5
};

这样封装重新赋值的时候，比如

function one(){

chartParam .containerId='sq2';

alert(chartParam .containerId);

}

function two(){

chartParam .containerId='sq3';

alert(chartParam .containerId);

}

同时调用这2个方法，会出问题，值会是sq3

下面的封装就好点了。

var ChartParam = {
createNew: function(){
var chartParam = {};

chartParam.containerId='sq1';
chartParam.titleText="";
chartParam.subtitleText="";           //无值不出现
chartParam.subtitleAlign=null;
chartParam.subtitleX=null;
chartParam.subtitleY=null;
chartParam.xAxisLabelsRotation=null;//为null就默认值，水平
chartParam.xAxisLabelsFontSize="12px";
chartParam.yAxisTickInterval=null;   
chartParam.yAxisTitleText="亿度";
chartParam.tooltipUnit="亿度";
chartParam.colors= new Array('#009966','#669999','#265430','#b7d275','#75780d','#9933CC','aa8f0e','#FFFFFF');//颜色数组
chartParam.type="spline";
chartParam.spacingTop=20;
chartParam.spacingRight=10;
chartParam.spacingBottom=5;
chartParam.spacingLeft=5;
return chartParam;
}
};
