openlayers显示问题

代码在html中可以正常显示，但放到jsp中，地图能显示，但是点的“LABEL”和颜色都不能动态显示，好像是${}没有接受到。为什么啊，刚开始搞openlayers，很多不明白啊，高手讲明白些

解决方案 »

  1.   

    我也遇见过这个问题，也是转换OpenLayers的html样例。html是不能直接转动态网页的，记得需要把里面的所有控件标签都改成jsp里的（我当时是.net）。你可以从网上找找html转jsp的文章。
      

  2.   

    UP  我也遇到这个问题，  在htm和jsp中不一样
    大家怎么解决的！
      

  3.   

    jsp和openlayers中 $冲突的问题
    可以这样 label:"<%="${label}"%>"
