在测试页面上,这可以找到静态变量:
<input class="txtSearch"
onblur="if(this.value == '')this.value='Search' ;"
onfocus="if(this.value == 'Search') this.value='';"
value="Search" name="s" type="text" size="15" />
当我把它放在我的页面中,用动态php切换静态变量时,我得到一个白页。我是否在函数内正确地逃避了它们?
function wpsb_show_form($rtn = 0) {
$wpsb_flds = (get_option('wpsb_form_fields'));
$add_link_lv = get_option("wpsb_link_love");
$out = '<form action="#wpsbw" method="post">' . "\n";
if (is_array($wpsb_flds)) {
foreach ($wpsb_flds as $wpsb_k => $wpsb_v) {
if (is_numeric($wpsb_k) && $wpsb_v) {
$out .= '<ul class="optin">';
$out .= '<li><span>Subscribe to our Newsletter</span></li>';
$out .= '<li><input type="text" name="wpsb_fld['. $wpsb_k .']" id="wpsb_fld_'. $wpsb_k .'" maxlength="64" class="txt" onblur="if(this.value == '') this.value="'. $wpsb_k .'" ;" onfocus="if(this.value == "'. $wpsb_k .'") this.value='';" value="'. $wpsb_k .'" /></label></li>' . "\n";
}
}
}
我是否需要转义javascript条件语句?
答案 0 :(得分:0)
您需要在输出javascript的行中转义单引号('
)。
记住:
print '\''; # output: '
print '"'; # output: "
print "'"; # output: '
print "\""; # output: "
