[原創]升級SOUI WKE以支持_blank

本文轉載自查看原文 2016-04-12 16:13 2278 wke/ blank/ SOUI/ webkit

由於WKE的精簡模式，導致原有的SOUI不支持針對諸多內容的調用，此處針對WKE的部分內容做升級，以支持對應的功能。

目的：使WKE可以_blank彈出新窗口。

由國人海綿寶寶維護的WKE新分支：https://github.com/cexer/wke

編譯新WKE的方式很簡單：

1、下載master，並解壓縮，如果有git就自己clone一下就好了

2、運行根目錄下的vs2008.bat，打開后直接編譯即可，時間根據CPU不同而不同。

SOUI的模式是動態加載函數，所以參考一下WKE頭文件，即可完成函數調用。

特別注意，SOUI的WKE.DLL中已經將WKE封裝為類，此處的WKE.DLL內是純C函數，無類，所以我們要自己寫。

如果懶得自己寫動態接口，就直接引用WKE.H就好了，然后連接一下WKE.LIB（這樣只是不太好剝離或按目錄加載庫）。

由於本人巨懶，懶癌晚期，所以我直接引用lib了，哈哈哈。

直接上點干貨
