更改 if else 语句中的 Jquery 变量
---原始代码----
$(function () {
var options = {
xaxis: { mode: "time", tickLength: 5 },
selection: { mode: "x" },
crosshair: { mode: "x" }
};
});
当rlt=true时，我希望crosshair: { mode: "x" }位于选项变量内部>。
以下是我的代码，但它不正确。有人可以指出错误吗？
谢谢！
$(function () {
var rlt = true;
var options;
if(rlt){
options = {
xaxis: { mode: "time", tickLength: 5 },
selection: { mode: "x" },
crosshair: { mode: "x" }
};
}else{
options = {
xaxis: { mode: "time", tickLength: 5 },
selection: { mode: "x" }
};
}
});
---Original code----
$(function () {
var options = {
xaxis: { mode: "time", tickLength: 5 },
selection: { mode: "x" },
crosshair: { mode: "x" }
};
});
I want crosshair: { mode: "x" } to be inside of options variable when rlt=true.
Following is my code, but it's not correct.Is there anyone can point error out?
Thanks!
$(function () {
var rlt = true;
var options;
if(rlt){
options = {
xaxis: { mode: "time", tickLength: 5 },
selection: { mode: "x" },
crosshair: { mode: "x" }
};
}else{
options = {
xaxis: { mode: "time", tickLength: 5 },
selection: { mode: "x" }
};
}
});

对我有用，但你可以这样写：
works for me, but you can write it this way:
如果您在
$(function () {}内检查options.crosshair.mode，您所拥有的将有效变量的作用域在哪里。
What you have works if you are checking
options.crosshair.modeinside the$(function () {}where the variable is scoped.
