页签控件的active事件，由于代码中的写法，会造成切换tab时，事件触发多次。
tui.ctrl.tab.ts中第35行中的部分代码：
private checkPage(button: any) {
var tabId = button.attr("data-tab");
tabId = "#" + tabId;
if (button.checked()) {
$(tabId).removeClass("tui-hidden");
tui.ctrl.initCtrls($(tabId)[0]);
} else {
$(tabId).addClass("tui-hidden");
}
this.fire("active", {index: this._buttons.indexOf(button), text: button.text()});
}
按我的理解，active事件的触发是不是应该改成下面的样子：
private checkPage(button: any) {
var tabId = button.attr("data-tab");
tabId = "#" + tabId;
if (button.checked()) {
$(tabId).removeClass("tui-hidden");
tui.ctrl.initCtrls($(tabId)[0]);
this.fire("active", {index: this._buttons.indexOf(button), text: button.text()});
} else {
$(tabId).addClass("tui-hidden");
}
}
只有被选中的那个tab页才激活事件，否则所有的tab页都会触发此事件。
如果是我的理解有误，请问我该如何正确使用active事件呢？谢谢。
tui.ctrl.checkbox.ts中的如下代码：
value(): any;
value(val?: any): Checkbox;
value(val?: any): any {
if (typeof val !== tui.undef) {
this.attr("data-value", JSON.stringify(val));
return this;
} else {
val = this.attr("data-value");
if (val === null) {
return null;
} else {
try {
return eval("(" + val + ")");
} catch (err) {
return null;
}
}
}
}
为什么不直接返回val变量，而是要返回“eval("(" + val + ")")”呢？这种情况下我没有办法正常取得设定好的data-value。
下面是我写的上传方法。其中有文件类型、文件大小错误的检查：
问题一：当在IE9下，以下代码发生异常，而firefox下正常。推测其它IE版本可能也有同样的问题；
问题二：后台检查失败后，我想显示自己返回的异常消息，但目前file控件中只显示自己的消息。
以上两个问题，希望可以给些建议，谢谢。
目前我有两个grid，想通过scrollbar实现两个grid联动（上下排列，共用同一个header），所以使用动了scrollbar.scroll事件，一个scrollbar变更了，则设置另一个scrollbar.value。但由于value方法中没有fire scroll事件，所以另一个grid并没有一同移动。
我目前的变通方法是在value方法中fire scroll事件。请帮忙看看是不是有问题，或者提供下其它实现方式，谢谢。
tui.ctrl.scrollbar.ts 现有代码：
value(val?: number): any {
if (typeof val === "number") {
val = Math.round(val);
if (val < 0)
val = 0;
if (val > this.total())
val = this.total();
this.attr("data-value", val);
this.refresh();
return this;
} else {
var val = parseInt(this.attr("data-value"), 10);
if (val === null || isNaN(val))
return 0;
else
return val;
}
}
修改后的代码：
value(val?: number): any {
if (typeof val === "number") {
val = Math.round(val);
if (val < 0)
val = 0;
if (val > this.total())
val = this.total();
var needFireScroll = false;
if (val != this.attr("data-value")) {
needFireScroll = true;
}
this.attr("data-value", val);
this.refresh();
if (needFireScroll) {
this.fire("scroll", { value: val, type: "valueChange" });
}
return this;
} else {
var val = parseInt(this.attr("data-value"), 10);
if (val === null || isNaN(val))
return 0;
else
return val;
}
}
两个Grid联动的代码：
var scrollbar1 = tui.ctrl.scrollbar($("#grid1 .tui-scrollbar[data-direction='horizontal']")[0]);
var scrollbar2 = tui.ctrl.scrollbar($("#grid2 .tui-scrollbar[data-direction='horizontal']")[0]);
scrollbar1.on("scroll", function(args) {
scrollbar2.value(args.value);
});
scrollbar2.on("scroll", function(args) {
scrollbar1.value(args.value);
});
