gsp，groovy，encodeURI组件，内联javascript [英] gsp, groovy, encodeURI component, inline javascript

问题描述

我有这个每个循环的问题

我有一个选择，你选择一个选项，按一个按钮，所选值通过ajax作为encodeURIcomponent被传递到后端，答案更新这个ul：

 < g：each in =$ {items}> 
< li class =$ {fieldName} _item> $ {it}< span onclick =deleteItem（'$ {fieldName}'，'$ {id}'，'$ {reloadForm} ，'$ {it}'）; class =editdropdel $ {fieldName} _button>< / span>< / li> 
< / g：each> 
  

一旦 $ {it} 特殊字符如内联的东西被打破，

有没有这样的可能？

  onclick =deleteItem（'$ {fieldName}'，'$ {id}'，'$ {reloadForm}'，'encodeURIcomponent（$ {it}）' 
  

我只是不明白

谢谢提前

解决方案

当然，当 $ {it} 包含，因为这有效地意味着您的onclick属性的值在第二个发生时终止。 / p>

encodeURIComponent当然不能帮助你，因为它太晚了 - 你不能调用JavaScript方法来修复破碎的HTML代码。

您想要的是将重写为& quot; 所以它不会结束属性值。对于哪种方法在你的模板语言中 - 请参考文档。

i have a problem with this each loop

i have a select, you choose an option, press a button and the selected value is beamed via ajax as encodeURIcomponent to the backend, the answer updates this ul :

<g:each in="${items}">
<li class="${fieldName}_item" >${it}<span onclick="deleteItem('${fieldName}','${id}','${reloadForm}', '${it}');" class="editdropdel ${fieldName}_button"></span></li>
</g:each>

as soon as ${it} contains special characters like " "" " the inline stuff is broken,

is there something like this possible ?

onclick="deleteItem('${fieldName}','${id}','${reloadForm}', 'encodeURIcomponent(${it})');"

i just don´t get it

thankws in advance

解决方案

Of course this breaks when ${it} contains ", because this effectively means that the value of your onclick attribute gets terminated where the second " occurs.

encodeURIComponent can of course not help you here, because it "comes too late" – you can not call a JavaScript method to fix broken HTML code.

What you want is to have the " rewritten to " – so that it does not end the attribute value. For which method does that in your template language – please consult docs.
