我正在爲W stream流場創建一個塊,它使用Prism JS庫顯示實時代碼語法高亮顯示。它部分工作;當我在的地方選擇的語言和代碼現有頁面上,代碼顯示出來,強調預期:W stream流場塊:將jQuery注入W Admin管理員
然而,當我嘗試用新的代碼塊創建一個新的鶺鴒頁,我得到一個JavaScript錯誤:
好像圖書館正在對延遲加載時沒有內容有它突出。我已經嘗試了$(document).ready
和$(window).load
,但這是一種不同的情況,因爲當您單擊「代碼段」按鈕時,包含Prism庫的模板將被動態加載。下面是我得到錯誤的分機:

下面是我使用的鶺鴒塊Django的鶺鴒代碼:
class CodeBlock(StructBlock):
"""
Code Highlighting Block
"""
WCB_LANGUAGES = get_language_choices()
language = ChoiceBlock(choices=WCB_LANGUAGES)
code = TextBlock()
class Meta:
icon = 'code'
template = 'wagtailcodeblock/code_block.html'
form_template = 'wagtailcodeblock/code_block_form.html'
...和表單模板的代碼該鶺鴒管理員:
<script>
function prism_repaint(target_class) {
Prism.highlightElement($(target_class)[0]);

function populate_target_code(label) {
target_class = '#target-element-' + label;

$(target_class).text(code_text);
prism_repaint(target_class);

我驗證過的CSS和JS正確地被注入到使用extra_css
和extra_js
模板塊的代碼。我也嘗試過使用「.getScript」函數,但沒有任何運氣。我絕不是JavaScript專家,所以任何幫助,將不勝感激。該項目的整個源可以在GitHub上找到,如果幫助:

任何幫助跟蹤解決這個將不勝感激!謝謝你的時間。
