【Legend】JOY PB(529058939) 18:25:11 The description information in the lower left corner, which is the information on the first few pages, how to modify it?

【Talk】RIAStudio(228456440) 18:26:29 show css or what

[Legend] JOY PB(529058939) 18:26:50 wait, let me take a screenshot

【话唠】RIAStudio(228 456440) 18:26:52 css, directly load a own css file

【Legend】JOY PB(529058939) 18: 27:11 not css, but the template content inside

【话唠】RIAStudio(228456440) 18:28:53 There are 4 parameters

[Legend] JOY PB(529058939) 18:28: 59 You write it all by yourself. . .

【话唠】RIAStudio(228456440) 18:29:05 This is its own, not universal < /div>

【Talk】RIAStudio(228456440) 18:29:52 What do these 4 parameter subtables represent? You can search descTemplate to find out where it matches

【話唠】RIAStudio(228456440) 18: 30:00 can definitely be changed

【Talk】RIAStudio(228456440) 18:30:22 but it needs to be modified by overloading, it is best not to directly modify the original control

< div style="float:left; margin-right:3px"> 【Legend】JOY PB(529058939) 18:31:07 enhancedGrid’s pagination plugin has nls

【Legend】JOY PB(529058939) 18:31:31 Yes, I don’t want to modify his source file.

【Legend】JOY PB(529058939) 18:41:42 will not extend

你要告诉我，你没用过dijit么。 . .

【话唠】RIAStudio(228456440) 18:28:53

有4个参数

【传说】JOY PB(529058939) 18:28:59

你全是自己写的。 . .

【话唠】RIAStudio(228456440) 18:29:05

这是它自己的，不是通用的

【传说】JOY PB(529058939) 18:29:32

能修改没

【话唠】RIAStudio(228456440) 18:29:52

这4个参数分表代表的是什么，可以搜索 descTemplate 找一下在哪里匹配的

【话唠】RIAStudio(228456440) 18:30:00

肯定可以改

【话唠】RIAStudio(228456440) 18:30:22

不过要通过重载来修改，最好不要直接改原控件

【传说】JOY PB(529058939) 18:30:45

【传说】JOY PB(529058939) 18:31:07

enhancedGrid的pagination插件里面有nls

【话唠】RIAStudio(228456440) 18:31:23

nls 是多国语言，跟这个没关系

【传说】JOY PB(529058939) 18:31:31

是啊，我也不想修改他的源文件

【话唠】RIAStudio(228456440) 18:32:03

等下，帮你找一下

【传说】JOY PB(529058939) 18:32:07

【传说】JOY PB(529058939) 18:32:24

这是它里面的调用

【话唠】RIAStudio(228456440) 18:36:38

dojox\grid\enhanced\nls\zh\Pagination.js这个文件的399行

_updateDescription: function(){
// summary:
// Update size information.
var s = this.plugin.forcePageStoreLayer,
maxSize = this.plugin._maxSize,
nls = this.plugin._nls,
getItemTitle = function(){
return maxSize <= 0 || maxSize == 1 ? nls[5] : nls[4];
};
if(this.description && this.descriptionDiv){
this.descriptionDiv.innerHTML = maxSize > 0 ? string.substitute(nls[0], [getItem Title(), maxSize, s.startIdx + 1, s.endIdx + 1]) : “0 ” + getItemTitle();
}
},
重载这个方法

【话唠】RIAStudio(228456440) 18:36:53

his.descriptionDiv.innerHTML = maxSize > 0 ? string.substitute(nls[0], [getItemTitle(), maxSize, s.startIdx + 1, s.endIdx + 1]) : “0 ” + getItemTitle();

【话唠】RIAStudio(228456440) 18:37:04

this.descriptionDiv.innerHTML = maxSize > 0 ? string.substitute(nls[0], [getItemTitle(), maxSize, s.startIdx + 1, s.endIdx + 1]) : “0 ” + getItemTitle();

【话唠】RIAStudio(228456440) 18:37:08

主要是这个

【话唠】RIAStudio(228456440) 18:37:17

string.substitute(nls[0],

【话唠】RIAStudio(228456440) 18:37:37

[getItemTitle(), maxSize, s.startIdx + 1, s.endIdx + 1]
这就是那4个参数

【传说】JOY PB(529058939) 18:39:53

_updateDescription这个貌似文档里面没有

【话唠】RIAStudio(228456440) 18:40:07

这是私有方法

【话唠】RIAStudio(228456440) 18:40:15

说了，不要看文档，直接看代码

【传说】JOY PB(529058939) 18:40:38

嗯，以后看代码

【话唠】RIAStudio(228456440) 18:40:39

用 extend 重载一下就可以了

【传说】JOY PB(529058939) 18:41:42

不会extend

【传说】JOY PB(529058939) 18:41:57

我刚学会create class

【话唠】RIAStudio(228456440) 18:42:00

【传说】JOY PB(529058939) 18:42:06

【话唠】RIAStudio(228456440) 18:42:30

等你学会了，就能体会到 dojo 真的是最好的 js 框架

【传说】JOY PB(5290 58939) 18:43:28

再教点吧，怎么extend

【话唠】RIAStudio(228456440) 18:44:54

require([“dojox\grid\enhanced\nls\zh\Pagination”], function(Pagination){   Pagination.extend({ _updateDescription: function(){ // summary: // Update size information. var s = this.plugin.forcePageStoreLayer, maxSize = this.plugin._maxSize, nls = this.plugin._nls, getItemTitle = function(){ return maxSize <= 0 || maxSize == 1 ? nls[5] : nls[4]; }; if(this.description && this.descriptionDiv){ this.descriptionDiv.innerHTML = maxSize > 0 ? string.substitute(nls[0], [getItemTitle(), maxSize, s.startIdx + 1, s.endIdx + 1]) : “0 ” + getItemTitle(); } },   }); });
